Find the next two terms of the following sequence 13, 4, - 11, - 32, ...

Enter the terms separated by a comma.

13 - 9 = 4, 4 - 15 = - 11, - 11 - 21 = - 32

What you're subtracting by increases by 6 each time.

The next two terms are - 59 and - 92; if you need me to explain this answer further, let me know.
