In the following question, a letter-number series is given with one term missing as shown by (?). Choose the missing term out of the given alternatives.
A95, F90, K85, ?, U75
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → P80
In a letter-number series, the letters and the numbers follow separate rules, so each part is checked on its own.
Letters A (1), F (6), K (11), ?, U (21): each is 5 places ahead, so the missing letter is 11 + 5 = 16, which is P
Numbers 95, 90, 85, ?, 75: each is 5 less, so the missing number is 80
