this is confusing! sorry i dont know :(

its kk here is de method....answered by sum1...

Look at the sequence:

0, 2, 5, 9, 14, ...

Each time, the difference goes up by 1.

You need to find two consecutive terms where the difference is 30. Just continue the sequence to find this value.

You could use algebra but it would be a waste of time.
