x*1+1;x*2+2;x*3+3...

Question:
DIRECTIONS: What should come at the place of question mark?
Q1F, S2E, U6D, W21C, ?
Options:
A) Y44B
B) Y66B
C) Y88B
D) Z88B
E) Z66B
Solution:
\(Q\xrightarrow {+2}S\xrightarrow {+2}U\xrightarrow {+2}W\xrightarrow {+2}[Y]\)

\(1\xrightarrow {X^1+1}2\xrightarrow {X^2+2}6\xrightarrow {X^3+3}21\xrightarrow {X^4+4}[88]\)

\(F\xrightarrow {-1}E\xrightarrow {-1}D\xrightarrow {-1}C\xrightarrow {-1}[B]\)
