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

The sequence alternates the arrangement of the letters 'c', 'b', and 'a'. After 'cbac', the next logical arrangement is 'ccba', which continues the pattern of using the same letters while rearranging them.

The series follows the pattern 'mam nam nam mam', where each segment builds upon 'm' and 'n', with vowels inserted in between. This leads to option C as the correct answer.

The first letter moves two steps forward. The last letter moves one step backward. 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

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

• R _ M becomes RAM by filling in A.
• R __ M becomes RAM by filling in A and M.
• ___M becomes RAM by filling in R, A, and M.

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

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

The letters are alternate and the numbers indicate their position in the alphabet from the beginning.

The series can be constructed by repeating 'bbabb' after the initial 'a', resulting in:

• a
• b b a b b
• rest of the series...

1. Identify the pattern by examining each term:

• Term 1: n m m n
• Term 2: m m n n (shift left once)
• Term 3: m n n m (shift left again)

2. Determine the next term by continuing the pattern:

• Term 4: n n m m

Thus, the correct answer is nnmm.

The intended pattern involves cyclically shifting letters, but none of the provided options align with this structure.

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.

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.
