Explanation

The pattern is +5, +7, +9, +11, +13, +15. 3+5=8, 8+7=15, 15+9=24, 24+11=35 (not 34), 35+13=48, 48+15=63. The wrong number is 34.

AI explanation

The pattern for this series is based on consecutive perfect squares starting from two squared. The numbers should be two squared, three squared, four squared, five squared, six squared, seven squared, and eight squared, which calculates to 4, 9, 16, 25, 36, 49, and 64. Since 34 is not equal to 36, it is the incorrect number in the sequence.
