Write the first five terms of the arithmetic sequence. a4 = 22, a10 = 64

Hello:

the general term is:

an = a1 + (n-1) * d

or : an = ap + (n-p) * d ... d is common diffrence

let : n=10 and p = 4

a10 = a4 + (10-4) * d

64 = 22 + 6d

6d = 42

d = 7

conclusion:

a4 = 22

a3 = 22-7=15

a2=15-7=8

a1 = 8-7=1

the first five terms : 1, 8, 15, 22
