Question

If 17 is to 291, then 26 is to __?

This question was previously asked in
SSC Selection Post 2025 Graduate Level Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

678

678 is correct.

Look for the rule linking 17 and 291. The square of 17 is \(17^2 = 289\), and \(289 + 2 = 291\). So the rule is: square the number and add 2.

Apply the same rule to 26: \(26^2 = 676\).

Adding 2: \(676 + 2 = 678\).

676 is only the square without the added 2, while 576 and 578 come from \(24^2\), so they do not follow the rule.
