A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
AKM, CMO, EOQ, GQS, ?

The logic here is

A + 2 = C $$\longrightarrow\ $$ C + 2 = E $$\longrightarrow\ $$ E + 2 = G $$\longrightarrow\ $$ G + 2 = I

K + 2 = M $$\longrightarrow\ $$M + 2 = O $$\longrightarrow\ $$O + 2 = Q $$\longrightarrow\ $$ Q + 2 = S

M + 2 = O $$\longrightarrow\ $$O + 2 = Q $$\longrightarrow\ $$Q + 2 = S $$\longrightarrow\ $$ S + 2 = U

$$\therefore\ $$The missing term in the series is ISU.

Hence, the correct answer is Option B
