The third term of an arithmetic sequence is 15 and when 20 is added to the third term the 8 term is obtained
a) What is the common difference of the sequence?
S
b) What is the position of 103 in this sequence?​

Common difference = 4

Position of 103 = 25th term

Step-by-step explanation:

a)

According to the given information:

Common difference = 4

b)

So, the position of 103 in this sequence is 25th term.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
