Correct Answer: IFQE
Solution :
Given:
MDSA, KERC, ?, GGPG, EHOI
Subtract 2 and 1 from the place value of the first and the third letters respectively, and add 1 and 2 to the place value of the second and third letters respectively of the previous term to get the next term in the series.
MDSA→M – 2 = K; D + 1 = E; S – 1 = R; A + 2 = C→KERC
KERC→K – 2 = I; E + 1 = F; R – 1 = Q; C + 2 = E→IFQE
IFQE→I – 2 = G; F + 1 = G; Q – 1 = P; E + 2 = G→GGPG
GGPG→G – 2 = E; G + 1 = H; P – 1 = O; G + 2 = I→EHOI
So, IFQE is the missing term of the given series. Hence, the first option is correct.
