Answer:

Step-by-step explanation:

9, 13, 17, 21, 25

We are adding 4 each time

9+4 = 13

13+4 =17

17+4 = 21

The common difference =4

a1 = 9

The formula is

an = a1+d(n-1) where n is the term number

an = 9+4(n-1)

We want the 10th term

a10 = 9+4(10-1)

= 9+4(9)

= 9+36

= 45

we have given that $\frac{1}{x^2}$ .

we need to express this interms of power of x .

we know that $\frac{1}{x^n} =x^-n$ .

in place of n we have 2 .so $\frac{1}{x^2} =x^-2$ .

so this will be the expression interms of power of x .
