D: Z88B

Best Answer

Explanation

Consider the series Q1F, S2E, U6D, W21C.

Find the next term.

Separate the term into three parts.

 

Consider the first terms of each code Q, S, U, W.

The next two letters from Q are R and S

The next two letters from S are T and

The next two letters from U are V and W.

The next two letters from W are X and Y.

Thus, the first term of the missing code is Y.

 

Consider the last terms of each code F, E, D, C.

The previous letter from F is E.

The previous letter from E is D.

The previous letter from D is C.

The previous letter from C is B.

Thus, the last term of the missing code is B.

Consider the middle terms of each code is 1, 2, 6, 21.

1x1+1=2

2x2+2=6

6x3+3=21

21x4+4=88

Thus, the middle term of the missing code is .

 

Correct Option is: (C)

Thus, the missing term in the given series Q1F, S2E, U6D,W21C is C Y88B:
