What should come in place of the question mark (?) in the given series based on the English alphabetical order?
AEO, XAM, UWK, RSI, ?

Correct option is C

Logic:
The first position follows the pattern of decreasing by 3.
The second position follows the pattern of decreasing by 4.
The third position follows the pattern of decreasing by 2.
Explanation:
First position:
A to X: -3
X to U: -3
U to R: -3
R to O: -3
Second position:
E to A: -4
A to W: -4
W to S: -4
S to O: -4
Third position:
O to M: -2
M to K: -2
K to I: -2
I to G: -2
Thus, the missing term in the series will be: OOG.
