Show answer & explanation
Correct answer: D
Explanation: The relationship pairs a perfect square with the next integer's square plus one.
For 25: 25 = 5^2, so the related number is (5 + 1)^2 + 1 = 36 + 1 = 37, which matches the given pair.
For 49: 49 = 7^2, so the related number is (7 + 1)^2 + 1 = 64 + 1 = 65. Therefore the missing term is 65.
