The Number which best Completes the sequence below is: 107 214 642 2,568 12,840

Yup, I agree wih CPhill.

The noticable pattern is multiplying by one more than what you multiplied the last number by.

107*2 = 214

214*3 = 642

642*4 = 2,568

2,568*5 = 12,840

12,840*6 = 77,040

Thanks, ND.......I should have been more explicit in explaining how I got my answer (like you did!!!)

I gave you some points and a thumbs-up, too!!!
