Find the odd pair out?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 17 : 295
In each pair, the second number is the square of the first number plus 4:
Option (1) 11 : 125 — \(11^{2}+4=121+4=125\)
Option (2) 33 : 1093 — \(33^{2}+4=1089+4=1093\)
Option (3) 35 : 1229 — \(35^{2}+4=1225+4=1229\)
Option (4) 17 : 295 — \(17^{2}+4=289+4=293\), not 295, so 17 : 295 is the odd pair out
