Question

what is the nth term of 7,4,1-2,-5,-8

Answer 1

Answer:

10-3n

Step-by-step explanation:

Given,

The A.P. series - 7, 4, 1, -2, -5, -8

The first term (a) = 7

The second term (t) = 4

The common difference(d)= t-a = 4 - 7 = -3

We can see that the AP goes on by decreasing by 3.

The expression of nth term of any AP = a + (n-1)d

We are given here, a = 7 and d = -3

so, substituting a = 7 and d = -3 in the equation to find the expression of the nth term of the AP

7 + (n-1)(-3) = 7 -3n + 3 = 10 - 3n

Ans) The nth term of the AP 7, 4, 1, -2, -5, -8 is 10-3n
