Find the number that will come next in the series given below.
27, 36, 46, 57, 69, ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 82
The series grows by uneven steps, so look at the difference between each pair of terms. The differences become one larger each time:
\(36-27=9\)
\(46-36=10\)
\(57-46=11\)
\(69-57=12\)
The next difference is 13, so the missing term is \(69+13=82\).
