Question : Directions: Which letter cluster will replace the question mark (?) to complete the given series?
ABCD, BDFD, CFID, ?, EJOD
Option 1: DHED
Option 2: DHDD
Option 3: DLHD
Option 4: DHLD
Correct Answer: DHLD
Solution :
Given:
ABCD, BDFD, CFID, ?, EJOD
In the given series, add 1, 2, and 3 to the place value of the first, second, and third letters. The fourth letter D remains constant.
ABCD→A + 1 = B; B + 2 = D; C + 3 = F; D
BDFD→B + 1 = C; D + 2 = F; F + 3 = I; D
CFID→C + 1 = D; F + 2 = H; I + 3 = L; D
DHLD→D + 1 = E; H + 2 = J; L + 3 = O; D
So, the missing term is DHLD. Hence, the fourth option is correct.
