What will come in place of question mark (?) in the following series
Z, X, U, Q, L, ?

Given: Z, X, U, Q, L, ?

Logic: The difference between consecutive letters is decreasing by 1 each time:

Z - 2 = X, X - 3 = U, U - 4 = Q, Q - 5 = L,

Same pattern follow continuously,

L - 6 = F

So, F is next term.

Thus, the correct answer is (d).
