Write a recursive formula for the sequence 180,160, 140, 120, 100...

g(n) = 180 - 20(n-1)

Step-by-step explanation:

Since your has its g(1) value as 180, we put 180 in front. Then, we subtract 20 multiplied by n-1, n being the sequence number. For example, if the recursive function has recursed 3 times, we do 3-1, which is 2. We multiply 2 with 20, which is 40. Finally, we subtract 40 from 180, which is 140. This equation is equivalent to g(3) = 180 - 20(3-1). When the sequence has g(3), we clearly see the answer is 140. When we look at the sequence, the third number is 140, proving this equation correct.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
