Question

Find the 10th term of the arithmetic sequence with the terms a1=15 and d=80

Answer 1

The 10th term is 735

Explanation:

The 10th term of an Arithmetic Sequence is given by:

`a_(10)=a_1+9d`

From the question, we were given that:

`a_(1)=15`

and

`d = 80`

We substitute these values into the above expresion to obtain:

`a_(10)=15+9 * 80`

`a_(10)=15+720`

`a_(10) = 735`
