Question

whoever does this will receive brainliest. Do any 1 Or if you do two I'll be really happy ​

Answer 1

Step-by-step explanation:

a³= 18. a¹⁷=?

so a+2d=18 -> 1

same as a⁷=30

so a+6d=30->2

a+2d=18. a &a get cancelled

a+6d=30

________

- 4d=-12

d=-12/-4 =3

d=3->1answer

a+2d=18 = a+2×3=18

a=18_6

a=12 ->2answer

to find a¹⁷= a+16d

12+16×3=60

1. a17=60

Answer 2

$\huge\fbox\bold\red{ANSWER}$

A3=18

a+2d=18.......(i)

A7=30

a+6d=30......(ii)

By Elimination method

4d=12

d=3

put d=3 in equation..(i)

a+2×3=18

a+6=18

a=12

$\huge\star\bold\red{NOW}$

A17=a+16d

=>12+16×3

=>12+48

=>60
