Answer :
Final answer:
The numbers in the sequence are perfect squares, and following the pattern, the next number in the series is 169, which is 13 squared. Therefore, the correct answer is c) 169.
Explanation:
The question asks for the next number in the series 64, 81, 100, 121, 144. To find the pattern, observe that these numbers are perfect squares: 64 is 8 squared (8 x 8), 81 is 9 squared (9 x 9), 100 is 10 squared (10 x 10), 121 is 11 squared (11 x 11), and 144 is 12 squared (12 x 12). Following this pattern, the next perfect square would be 13 squared (13 x 13), which equals 169.
