Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?

ICV 16, LGS 5, OKP -6, ROM -17, ?

Given: ICV 16, LGS 5, OKP -6, ROM -17, ?

Logic: 1st letter + 3, 2nd letter + 4, 3rd letter - 3 and number is decreasing - 11 place.

For, 1st letter

I + 3 = L, L + 3 = O, O + 3 = R, R + 3 = U

For, 2nd letter

C + 4 = G, G + 4 = K, K + 4 = O, O + 4 = S

For, 3rd letter

V - 3 = S, S - 3 = P, P - 3 = M, M - 3 = J

For, number

16 - 11 = 5, 5 - 11 = -6, -6 - 11 = -17, -17 - 11 = -28

So, the missing term is USJ -28.

Thus, correct option is (c).
