Which of the following terms will replace the question mark (?) in the given series to make it logically complete?
LBW 1, NEU -2, PHS -5, RKQ -8, ?

Given: LBW 1, NEU -2, PHS -5, RKQ -8, ?

Logic: 1st letter + 2, 2nd letter + 3, 3rd letter - 2 and number is decreases by 3 place.

For, 1st letter

L + 2 = N, N + 2 = P, P + 2 = R, R + 2 = T

For, 2nd letter

B + 3 = E, E + 3 = H, H + 3 = K, K + 3 = N

For, 3rd letter

W - 2 = U, U - 2 = S, S - 2 = Q, Q - 2 = O

For, number

1 - 3 = -2, - 2 - 3 = -5, -5 - 3 = -8, -8 - 3 = -11

So, the missing term is TNO -11.

Thus, correct option is (c).
