Alpha Numeric: Reasoning Questions & Answers – Free Practice!

Ans: A) O25

The alphabetical sequence progresses as A, C, F, J, …

A (+2) → C (+3) → F (+4) → J (+5).
The numerical sequence is 1, 4, 9, 16 (perfect squares of consecutive integers).
Next alphabet: J (+5) = O.
Next square: $16 + 2^2 = 25$

Ans: B) 32P

The numbers double each time: 2,4,8,16,32
The letters follow the pattern B (+2) → D (+3) → G (+4) → K (+5).
Next letter: K (+5) = P.

Ans: D) K33K

Letter sequence: A (+1) → B (+2) → D (+3) → G (+4). Next: G (+5) = K.
Number sequence: 3,5,9,17 (doubling the difference: +2,+4,+8 ). Next: 17+16=33

Letter sequence 2: B (+3) → E (+3) → H (+3) → K (+3). Next: K (+3) = N.

Ans: B. 30U

Number sequence: 2,6,12,20 (differences are +4,+6,+8). Next: 20+10=30
Letter sequence: C (+3) → F (+4) → J (+5) → O (+6). Next: O (+7) = U.

Ans: C. O30R

Letter sequence 1: A (+2) → C (+3) → F (+4) → J (+5). Next: J (+6) = O.
Number sequence: 2,6,12,20 (differences +4,+6,+8). Next: 20+10=30
Letter sequence 2: Z (-2) → X (-2) → V (-2) → T (-2). Next: T (-2) = R.
