What should come in place of the '?' in the given series: BZA, CXB, EVC, GTE, ?
IRG
ISF
IRH
JRG
IRG
Observe the three positions in the triplet separately: position 1 increases by steps of +1, +2, +2, +2; position 2 decreases by -2, -2, -2, -2; position 3 follows the sequence A(1), B(2), C(3), E(5), which are prime indices or specific jumps.

Analyze the 1st letter of each triplet
B(2) to C(3) is +1, C(3) to E(5) is +2, E(5) to G(7) is +2, G(7) to ? must be +2, resulting in I(9).
Analyze the 2nd letter of each triplet
Z(26) to X(24) is -2, X(24) to V(22) is -2, V(22) to T(20) is -2, T(20) to ? must be -2, resulting in R(18).
Analyze the 3rd letter of each triplet
A(1) to B(2) is +1, B(2) to C(3) is +1, C(3) to E(5) is +2, E(5) to ? must be +2, resulting in G(7).
B: ISF is wrong because the 2nd letter must be R and the 3rd G. C: IRH is wrong because the 3rd letter follows the increment pattern of 1, 1, 2, 2, leading to G. D: JRG is wrong because the first letter follows the sequence B, C, E, G which increments to I, not J.
A is correct because the series follows a consistent logic: 1st letter +1/+2/+2/+2 (I), 2nd letter -2/-2/-2/-2 (R), and 3rd letter +1/+1/+2/+2 (G), forming IRG.
For triplet series, always decompose the sequence into three individual parallel series to solve them in parallel rather than looking at the word as a whole.
