Answer:

you keep subtracting 2 every time, that's the pattern

Hey there!

We can see we are subtracting 2 every time, and we have 95 terms left fo figure out, so we multiply 95 by 2 and get 190, then subtract that from 15.

15 - 190 = -175, therefore, that's the the 100th term.

Have a terrifcly amazing day!
