Which letter cluster should come next in the following series? ADGJ, EEHK, IFIL, ?

Show answer & explanation

Correct answer: A

Explanation

Series: ADGJ, EEHK, IFIL, ?

examine the sequence letter by letter.

First letters:

A →E→ I

Positions in alphabet: A(1), E(5), I(9)

Pattern: +4 each time.

Next: I(9) + 4 = M(13)

Second letters:

D → E→F

Positions: D(4), E(5), F(6)

Pattern: +1 each time.

Next: F(6) + 1 = G(7)

Third letters:

G → H→ I

Positions: G(7), H(8), I(9)

Pattern: +1 each time.

Next: I(9) + 1 = J(10)

Fourth letters:

J → K → L

Positions: J(10), K(11), L(12)

Pattern: +1 each time.

Next: L(12) + 1 = M(13)

So, the missing term is MGJM

Hence, the correct answer is option (1).
