Answer 1

your ans

given:-

last term =-22

a=5

d=-3

use formula

l=a+(n-1)×d

-22=5+(n-1)×-3

-22-5=-3n+3

-22-5-3=-3n

-30=-3n

n=10

Answer 2

here you go ☆☆


given:-

a = 5
d = 2-5 => -3

a(n) = a + (n-1)d

-22 = 5 + (n-1)-3

-22-5 = -3n + 3

-27 = -3(n1-)

n-1=9

n = 9+1 => 10


so 10th term of AP is -22
