In the given question, find the next term in the alpha-numeric series?
Z1A, X2D, V6G, T21J, ...?..., P445P
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → R88M
The first letters run backwards two steps at a time — Z, X, V, T → R → P — and the last letters run forward three at a time — A, D, G, J → M → P.
For the numbers the rule is multiply by the term number and add the same number: 1 × 1 + 1 = 2, 2 × 2 + 2 = 6, 6 × 3 + 3 = 21, 21 × 4 + 4 = 88, and 88 × 5 + 5 = 445, which matches the last term. The missing term is R88M.
