Select the letter from among the given options that can replace the question mark (?) in the following series.
Y, W, T, P, K, ?
- AG
- BH
- CF
- DE
Solution & Step-by-step Explanation
Let's find the numerical position values of the given letters (Y=25,W=23,T=20,P=16,K=11):
Y(25)→W(23) : Difference =−2
W(23)→T(20) : Difference =−3
T(20)→P(16) : Difference =−4
P(16)→K(11) : Difference =−5
Following this increasing negative integer sequence, the next difference must be −6:
11−6=5
The letter corresponding to position value 5 is E.
Y(25)→W(23) : Difference =−2
W(23)→T(20) : Difference =−3
T(20)→P(16) : Difference =−4
P(16)→K(11) : Difference =−5
Following this increasing negative integer sequence, the next difference must be −6:
11−6=5
The letter corresponding to position value 5 is E.
