Question

For the sequence an = 3n - 5, what is the value of a30?

Answer 1

an= 3*30-5=85 so the answer is 85

Answer 2

`a_(30)=85`

Explanation:

The given sequence is
`a_n=3n-5`

In order to find the value of
`a_(30)`, plug n = 30 in the given sequence

`a_(30)=3*30-5`

Now, simplify it to find the value of
`a_(30)`

`90-5\\\\=85`

Therefore, the value of
`a_(30)` is 85.
