1st term = 1
2nd term = 1 + 5 = 6
3rd term = 6 + (5+4) = 6 + 9 = 15
4th term = 15 + (9+4) = 15 + 13 = 28
5th term = 28 + (13+4) = 28 + 17 = 45
6th term = 45 + (17+4) = 45 + 21 = 66
7th term = 66 + (21+4) = 66 + 25 = 91

Thus, the missing number is 4th term= 15 + (9+4) = 15+13 = 28

There are 8 triangles in the figure. By counting the individual triangles, we can see that there are 2 large triangles, 4 medium triangles, and 2 small triangles, making a total of 8 triangles.

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
So lightest in weight is C.

1st term = 2
2nd term = 2 + 3 = 5
3rd term = 5 + 4 = 9
4th term = 9 + 5 = 14
5th term = 14 + 6 = 20
6th term = 20 + 7 = 27

Thus, Missing number is 4th term = 14

• DRAM or Dynamic Random Access Memory is a specific type of RAM that stores bits of data in transistors. DRAM is located close to the processor, so that the computer can quickly access it for all the processes.
• PROM or Programmable ROM is a memory that can be programmed once after it is created. Once it is programmed, the data written is permanent and cannot be deleted. An example of PROM is a computer BIOS.
• EPROM or Erasable Programmable ROM is a memory that can retain the data even if there is no power supply. This data can be erased and reprogrammed by using UV light. The process of programming an EPROM is called Burning and the box into which it is plugged to program it is EPROM Burner.

To return the desired result "MCQ@ Questions" in cell C1, you can use the CONCATENATE function or the ampersand (&) operator in Excel.
Here is the detailed solution:
1. The correct function to use in this case is the CONCATENATE function or the ampersand (&) operator.
2. The CONCATENATE function allows you to join multiple text strings together. It takes multiple arguments and concatenates them into a single string.
3. The ampersand (&) operator also performs the same function as the CONCATENATE function and joins text strings together.
4. In this case, you want to join the value in cell A1 ("MCQ") with the text string "@" and the value in cell B1 ("Questions").
5. To achieve this, you can use the following formula in cell C1:
=CONCATENATE(A1, "@", B1) or =A1 & "@" & B1
This formula will concatenate the text in A1, the "@" symbol, and the text in B1, resulting in the desired output "MCQ@ Questions" in cell C1.
Therefore, the correct answer is option C: =A1 & "@" & B1.

Modulator-demodulator
A modulator-demodulator, also known as a modem, is a device that converts signals between digital and analog form. It is commonly used to transmit data over telephone lines.
Functions of a Modem
- Modulation: The modem converts digital data into analog signals that can be transmitted over analog communication channels such as telephone lines. This process is called modulation.
- Demodulation: On the receiving end, the modem converts the analog signals back into digital data. This process is called demodulation.
Conversion Process
- Digital to Analog Conversion: The modem takes digital signals consisting of 0s and 1s and converts them into analog signals that can be transmitted over analog channels. This conversion process involves techniques such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM).
- Analog to Digital Conversion: On the receiving end, the modem takes the analog signals and converts them back into digital signals. This conversion process involves techniques such as amplitude demodulation (ADM), frequency demodulation (FDM), or phase demodulation (PDM).
Modem Types
- Analog Modem: Converts digital signals to analog signals for transmission over analog communication channels.
- Digital Modem: Converts analog signals to digital signals for transmission over digital communication channels.
Conclusion
A modulator-demodulator, or modem, is a device that performs the conversion between digital and analog signals. It converts digital signals into analog signals for transmission and converts analog signals back into digital signals for reception. Therefore, the correct answer is C: Both A and B.

Use structure “By + question word + auxiliary + past participle + object ?”
As per the given above sentence is given in Passive Voice.
By whom was it written?
Therefore , option B will be required answer .

Use structure “subject + auxiliary + past participle + by + object”
As per the given above sentence is given in Passive Voice.
I remember being taken to the museum by my sister.

Shallow: Typically describes a lack of depth in character, thought, or emotion.

Superficial: This term also suggests a lack of depth, but it often refers to things that are only on the surface or are concerned primarily with appearances rather than substance.

Let us first learn the meanings of the given words:

Crucially (adverb): with decisive or vital importance.

Significant (adjective): sufficiently great or important to be worthy of attention.

Petty (adjective): of little importance.

The sentence implies that a large portion of the hospital bills was out of insurance coverage, thus ‘petty’ is contradictory. The use of ‘crucially’ is grammatically inapt as we need an adjective to qualify noun ‘portion’. The use of ‘obvious’ is contextually weak. Only ‘significant’ fits the blank grammatically and contextually.

Hence, option C is correct.

As per the given above sentence is given in Passive Voice.
Use structure “auxiliary + past participle”
Grass is not eaten by a lion, however hungry he may be.
Hence , option A will be correct answer .
