Question

Find th
nth term of
A.P
8,3-2,-7......​

Answer 1

Here, a = 8

d = 3-8 = -5

Thus,

Tn = a + (n-1)d.

= 8 + (n-1)(-5)

= 8 - 5n + 5

= 13 - 5n

Answer 2

AP -» 8, 3, -2, -7, ......

First term (a) = 8

Difference (d) = 3 - 8 = -5

Let nth term be 'T(n)' and is given by:

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

= 8 + -5(n - 1)

= 8 - 5n + 5

= 13 - 5n

Hence, nth term of the given arithmetic progression is given as T(n) = 13 - 5n
