What will come in place of the question mark (?) in the following series?
30, 41, 53, 66, 80, ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 95
Look at the difference between each pair of terms. The differences become one larger each time:
\(41-30=11\)
\(53-41=12\)
\(66-53=13\)
\(80-66=14\)
The next difference is 15, so the missing term is \(80+15=95\).
