Find the missing term in the series:
B12D, G32I, L52N, ?, V92X
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Q72S
In a letter-number series, each part of the term follows its own rule, so the first letters, the numbers and the last letters are checked separately.
First letters B, G, L, ?, V (2, 7, 12, ?, 22):
5 places ahead each time
So the missing letter is 17th, Q
Numbers 12, 32, 52, ?, 92:
20 more each time
So the missing number is 72
Last letters D, I, N, ?, X (4, 9, 14, ?, 24):
5 places ahead each time
So the missing letter is 19th, S
The missing term is Q72S.
