Question

Find the 64th term of the arithmetic sequence -28,-13,2

Answer 1

`a_(64)=917`

Explanation:

Given that,

The arithmetic sequence is :

-28,-13,2

First term = -28

Common difference = -13-(-28) = 15

We need to find the 64th term of the sequence. The nth term of the sequence is given by :

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

Put all the values,

`a_(64)=-28+(64-1)15\\\\=917`

So, the 64th term of the sequence is equal to 917.
