Question

40 POINTS AND BRAINLIEST

Answer 1

Answer:

-110

Step-by-step explanation:

Going from x=1 to 2, y decreases by 3 from 7 to 4

Going from x =2 to 3, y decreases by 3 from 4 to 1

We subtract 3 each time x increases by 1

The formula for an arithmetic sequence is

an = a1 + d(n-1)

where a1 is the first term a1 =7

d is the common difference or what we add (which is in this case is -3)

n is the term number we are looking for n= 40

a40 = 7 -3(40-1)

a40 = 7 -3(39)

a40 = 7 -117

a40 = -110
