Olympiad Test : Series And Pattern - 1 - Class 5 MCQ

Each term in the series is obtained by multiplying the previous term by 2.

Since 16 × 2 = 32, the next term is 32.

Therefore the correct option is C.

First letters:
Q → S → U → W → Y, each moves forward by 2 letters.

Middle Numbers follow the pattern a x n + n where (a is previous number and n is natural number: 1,2,3,4....)
The number series runs as below:
1 x 1 + 1 = 2
2 x 2 + 2 = 6
6 x 3 + 3 = 21
21 x 4 + 4 = 88

Last letters: F → E → D → C → B, each moves one step backward.

Combining these gives Y88B, hence option D.

The series is based on repeating the pattern 'RAM'. Breaking it down:

Thus, each segment completes to form RAM, making option C correct.

The series is bcaa/bcaa/bcaa/bcaa. Thus, the pattern 'bcaa' is repeated.

Letters pattern:
D → F → H → J → L → N
(Each letter skips one alphabet: +2 positions)

Numbers pattern:
4 → 6 → 8 → 10 → 12 → 14
(Each number increases by +2)

So the missing elements are L-12 and N-14.

Answer:
D) I

Explanation:
The series is skipping one letter each time:
A (skip B) → C (skip D) → E (skip F) → G (skip H) → I

Therefore the correct option is nnmm (option C).

The series starts with 'ccc', indicating three 'c's. Following that, it should have 'bbb' (three 'b's), but due to a typo or misplacement, it shows 'bb'.

After the first blank, it continues with 'aa', which suggests the next set should be 'aaa'. Therefore, the missing segment after 'cccbb' is 'baa'.

The series is abadna/abadna/abadna/ab. The pattern ‘abadna’ is repeated.

Let’s find the difference between each pair of numbers:

We observe that the differences are:
+4, +6, +8
These are increasing by +2 each time.
So the next difference should be:
+10

Now, Add +10 to the last term:
20 + 10 = 30

So, the next number in the pattern will be 30

The first letter of the terms are alternate. The sequence followed by the numbers is +2, +3, +4,.... The last letter is three steps ahead of the last letter of the preceding term.

The letters move 1, 2, 3, ... steps forward. The numbers increase by + 3, + 5, + 7, + 9....

The first numbers in the terms follow the sequence x 2, x 3, x 4. The letter moves three steps forward. The last numbers follow the sequence + 2, + 4, + 6.
