Answer:
[tex]a_7=-15[/tex]
Step-by-step explanation:
[tex]a_n[/tex] is given as the nth term of a sequence.
We want to find [tex]a_7[/tex] , which means we find the 7th term of the sequence.
Here, we simply substitute "7" into "n" of the formula given for [tex]a_n[/tex] to find the value of the 7th term of the sequence.
We show this below:
[tex]a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15[/tex]
So the 7th term is "-15"
