Answer:
The 89th term would be 895.
Step-by-step explanation:
There is a pattern of adding 10 each time. Notice that the 5 at the end doesn't change and that the first number continues (i.e. 2, 3, 4, 5, 6). All you have to do is add an 89 in front of the 5 and that is your answer, 895.
I might not know the answer to this question but I hope you find one
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
