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

Answer:

$a_{30}=85$

Step-by-step 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

$a_{30}=3\times30-5$

Now, simplify it to find the value of $a_{30}$

$90-5\\\\=85$

Therefore, the value of $a_{30}$ is 85.
