Find Sn for the given arithmetic series.
Q1 = -40, d =-7, n=22

-2497

Step-by-step explanation:

We are given an arithmetic series with the following terms:

First term, = -40

Common difference, d = -7

Number of terms, n = 22

To find out: Sum of n terms, where n is 22

We know that Sum of n terms in an arithmetic series is given as:

Putting the values in the formula:

So, the sum of 22 terms is -2497.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
