Show answer & explanation
Correct answer: B
Correct answer: 26 is the wrong number. The intended series is the sequence of perfect squares: 1^2 = 1, 2^2 = 4, 3^2 = 9, 4^2 = 16, 5^2 = 25, 6^2 = 36, and 7^2 = 49. Therefore the sixth term should be 36, but the given term is 26. Hence, 26 is the wrong number.
