Question

A(n) = -6 + 3(n-1)

Find the 16th term in the expression.

Answer 1

The 16th term in the expression is 39

Explanation:

we have

`a(n)=-6+3(n-1)`

we know that

To find out the 16th term, substitute the value of n=16 in the expression above

so

For n=16

substitute

`a(16)=-6+3(16-1)`

`a(16)=-6+3(15)`

`a(16)=-6+45`

`a(16)=39`

therefore

The 16th term in the expression is 39
