Look at this series: 2, 30, 130, 350....... What number should come next?526650738810

This series seems to be increasing in a pattern. Let's try to figure out the pattern:

• The difference between 30 and 2 is 28.
• The difference between 130 and 30 is 100.
• The difference between 350 and 130 is 220.

It seems like the difference between each pair of numbers is increasing by 72 each time (100-28=72, 220-100=72).

So, if we add 72 to 220, we get 292.

If we add this difference to the last number in the series (350), we get 642.

So, the next number in the series should be 642.
