Answer 2

Hi,

The numbers come in groups of 3 consecutive numbers, 1-2-3, then 7-8-9, and finally 28-29-30.

If you look for a pattern for the first of those numbers, 1, 7, 28, they fit to the equation y = 7.5x² - 16.5x + 10. If we look at the formula for the 4th starting point, it is 64. So, the next group of 3 numbers would be 64, 65 and 66. <==ANSWER

I hope that helps!! :-)

Answer 3

Here's my reasoning:

1, 2, 3        (*2+1) = 7

7, 8, 9        (*3+1) = 28

28, 29, 30   (*4+1) = 121

So the next three numbers are:

121,122,123

Make sense?
