What should come in place of the question mark (?) in the following series? BDF, EGI, HJL, KMO, ?
NPR
NPQ
NPS
NPT

Observe the first letter of each group; they follow a +3 increment (B=2, E=5, H=8, K=11, N=14). Each subsequent letter within the group also follows a +2 jump (e.g., B+2=D, D+2=F).
Observe the first letter of each group; they follow a +3 increment (B=2, E=5, H=8, K=11, N=14). Each subsequent letter within the group also follows a +2 jump (e.g., B+2=D, D+2=F).
Analyze the first letters of each triplet
The first letters are B(2), E(5), H(8), K(11). Following the +3 pattern, the next letter is 11 + 3 = 14, which corresponds to N.
Analyze the second and third letters of the triplets
Each triplet follows a +2 sequence for every letter: B(+2)=D, D(+2)=F; E(+2)=G, G(+2)=I; H(+2)=J, J(+2)=L; K(+2)=M, M(+2)=O. Following this for N: N(+2)=P, P(+2)=R.
B: NPQ fails because the final letter Q is 17, but the pattern requires 18 (R). C: NPS fails because the final letter S is 19, which disrupts the +2 pattern from P. D: NPT fails because the final letter T is 20, which disrupts the +2 pattern from P.
A is correct because the series follows a consistent pattern where the first letter increments by +3 and every letter within the triplet increments by +2, resulting in N, P, and R.
Always map letters to their numerical positions (A=1, B=2, ..., Z=26) first; this turns visual pattern problems into simple arithmetic, reducing errors significantly.
