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

P80

The correct answer is Option (2) → P80

Look at the letter and number patterns separately.

Letter pattern:

A → F → K → ? → U

Each step moves +5 letters forward in the alphabet:

• A → F (+5)
• F → K (+5)
• K → P (+5)
• P → U (+5)

So the missing letter is P.

Number pattern:

95 → 90 → 85 → ? → 75

Each step decreases by 5:

• 95 → 90 (−5)
• 90 → 85 (−5)
• 85 → 80 (−5)
• 80 → 75 (−5)

So the missing number is 80.

Missing term: P80
