Find the missing term in the given series.5, 10, 17, ?, 37

The correct answer is Option (3) → 26

Each term is one more than a perfect square, the squares of 2, 3, 4, 5 and 6 in turn (the differences 5, 7, 9, 11 go up by 2).

• \(2^2+1=5\), \(3^2+1=10\), \(4^2+1=17\)

• Missing term \(=5^2+1=26\)

• Next \(6^2+1=37\), as given
