Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ITB.
Given series: GEA, IFB, LHA, QKB, XOA, ?
G + 2 = I; I + 3 = L; L + 5 = Q; Q + 7 = X; X + 9 = I
E + 1 = F; F + 2 = H; H + 3 = K; K + 4 = O; O + 5 = T
A + 1 = B; B - 1 = A; A + 1 = B; B - 1 = A; A + 1 = B
