Find the group of wrong alphabets in the following series.
M, C, P, F, T, G, Y

Correct option is D

Given series is combination series of two series of
first series - 1st, 3rd, 5th .....
second series is - 2nd, 4th .....
Both thd series increased by consecutive numbers starting by 3 respectively
according to this
C +3 = F
F + 4 = J should be here in place of G

G is wrong letter here.

Gap after F should be 4 and the correct series will be
M, C, P, F, T, J, Y
Hence, ‘G’ correct answer.
