100, 121, 144, 169. The patern is that the numbers are the fist nine integers above zero multiplied by themselves in order from least to greatest.

You have too many commas. Its 1, 4, 9, 16, 25, 36, 49, 64, 81. The next four numbers are 100, 121, 144, 169. The pattern is adding sequential odd numbers: 1 + 3 = 4 4 + 5 9 + 7 16 + 9 etc etc
