Question

In the Ap -5,-2,1,4,7....what will be the 20 term

Answer 1

a = -5
d = -2 - (-5)
= -2 + 5
= 3
n = 20
nth term = a + (n-1)d
20th term = -5 + (20-1)(3)
= -5 + (19)(3)
= -5 + 57
= 52
So the 20th term of this A.P. is 52

Answer 2

AP is -5, -2, 1, 4, 7......

a = -5
d = -2+5 = 3

A20 = a + 19d
= -5 + 19 * 3
= -5 + 57
= 52.
