Test: Patterns Around Us - Class 4 MCQ

• The number 17 is different from the others.

• All other numbers (12, 14, 20) are even.

• Number 17 is odd.

To find the total number of odd numbers between 1 and 100:

• Odd numbers start at 1 and go up to 99.
• They form an arithmetic sequence with a difference of 2.
• The sequence is: 1, 3, 5, ..., 99.
• The formula for the number of terms in an arithmetic sequence is: (last term - first term) / difference + 1.
• Using this: (99 - 1) / 2 + 1 = 49 + 1 = 50.

Thus, there are 50 odd numbers between 1 and 100.

The solution to the question of whether 4 is an even or odd number is as follows:

• 4 is an even number.
• This is because even numbers are integers that can be divided by 2 without leaving a remainder.
• In this case, 4 divided by 2 equals 2, with no remainder.

The pattern involves identifying which numbers are odd and which are even.

• Even numbers are divisible by 2 without a remainder.
• Odd numbers have a remainder of 1 when divided by 2.

In the given solution:

• Eight is an even number.
• Nine is an odd number.

This pattern correctly identifies that nine is odd, thus demonstrating a correct pattern for odd numbers.

• The arrangement forms a circular pattern.

• The fruits are arranged around the apple in a circle.

To find how many even numbers are between 1 and 20:

• The even numbers between 1 and 20 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.
• Count these numbers to find the total.
• There are 10 even numbers.

Even numbers are precisely defined as all multiples of 2. This means that any number that can be divided by 2 without leaving a remainder is categorized as even. 

Odd numbers have distinct characteristics:

• They are not multiples of 2.
• When grouped, they leave one unpaired.

The pattern of 10 consecutive numbers starting from 1 is as follows:

• The numbers alternate between odd and even.
• This means every second number is even, and the others are odd.

An even number is a number that is divisible by 2 without leaving a remainder. Here are the steps to identify an even number:

• Check if the number ends in 0, 2, 4, 6, or 8.
• If it does, the number is even.

In this case, 56 ends with a 6, which is an even digit, making it an even number.

The pattern follows a sequence of Circle, Square, Triangle.

Since the sequence repeats, the shape that follows the Square is a Triangle.

Thus, the statement that the next shape is a triangle is correct.

The next term will come by multiplying with number 2

12 × 2 = 24,

24 × 2 = 48,

48 × 2 = 96,

96 × 2 = 192,

192 × 2 = 384

Since the ball is falling down gradually in the box; the next pattern will be A. 

In the pattern, it can be seen that lines are increasing diagonally. 

The next pattern in the series will be D.

The given problem is a simple multiplication question. Here is how to solve it:

• Multiply the number 7 by 2.
• The result is 14.
