deff fn [24]
The equation for this is a^2+b^2=c^2 so your equation would be 7^2+20^2=X
So you square the 7 and the 20 then take the square root of X and you get

The sequence an = one third(3)n − 1 is graphed below: coordinate plane showing the points 2, 1; 3, 3; and 4, 9 Find the average
Maru [420]
The given sequence is:

a(n)= \frac{1}{3}  (3)^{n-1}

a(2)=1
a(3)=3
a(4)=9

We are to find the average rate of change between n=3 and n=4 for the given function.

Average rate of change = \frac{a(4)-a(3)}{4-3} = \frac{9-3}{1}=6

So the average rate of change for the given function from n = 3 to n = 4 is 6
