Mercedes Reynolds · Answer 1

4n-1

Step-by-step explanation:

The difference in the numbers is 4 so the coefficient must be 4 for the nth term meaning

4n

11 is the third term however we need to find the first so ...

11=3rd term

-4

7=2nd term

-4

3=1st term

now we need to minus 4 from 3 which is - 1 (3-4)

meaning the answer put together will be 4n-1
