Answer 1

Answer:

$a_7=-15$

Step-by-step explanation:

$a_n$  is given as the nth term of a sequence.

We want to find $a_7$ , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for  $a_n$  to find the value of the 7th term of the sequence.

We show this below:

$a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15$

So the 7th term is "-15"
