Find the next three terms in the sequence

Question

3,12,21,30….

Answer 1

The given sequence seems to be an arithmetic sequence with a common difference of 9. Thus, to find the next three terms:

* Add 9 to the last term, 30, to get 39.
* Add 9 to the term 39 to get 48.
* Add 9 to the term 48 to get 57.

Therefore, the next three terms in the sequence are 39, 48, and 57.
