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
Each term has three parts, and each part follows its own rule:
First letters Z, X, V, T: each is two places back in the alphabet, so the next is R (and then P, as given)
Numbers 1, 2, 6, 21: each is the one before it multiplied by 1, 2, 3, 4 ... and then increased by the same number:
\(1\times1+1=2\), \(2\times2+2=6\), \(6\times3+3=21\)
\(21\times4+4=\) 88, and then \(88\times5+5=445\), as given
Last letters A, D, G, J: each is three places forward, so the next is M (and then P, as given)
