Question

Select the option that represents the letters that, when sequentially placed from left to right in the blanks below, will complete the letter series. _ D _ L _ F _ O L J

• A. FOJD
• B. DJOF
• C. JDOF
• D. OJDF

Answer 1

Answer:

A. FOJD

Series:
_ D L F _ O L J

Now separate into two alternating sequences.

Odd positions (1,3,5,7,9):

F, O, J, D, L

Alphabet positions:
F = 6
O = 15
J = 10
D = 4
L = 12

Pattern:
6 → 15 (+9)
15 → 10 (−5)
10 → 4 (−6)
4 → 12 (+8)

Now check even positions (2,4,6,8,10):

D, L, F, O, J

Alphabet positions:
4 → 12 (+8)
12 → 6 (−6)
6 → 15 (+9)
15 → 10 (−5)

This follows a repeating pattern:

+8, −6, +9, −5

Both sequences follow the same cyclic pattern.

So the letters that correctly complete the series are:

FOJD
