This formula means that a(n) for n, when n is the term number, will give you the term. Meaning, we just have to plug in 55 for n.
a(55) = -1 + 3(55 - 1)
a(55) = -1 + 3 * 54
a(55) = -1 + 162
a(55) = 161
Answer:
[tex]\bold{161}[/tex]
Step-by-step explanation:
We know that [tex]n[/tex] here is represented by 55 (nth term = 55th term), so we get the 55th term is
-1 + 3(55 - 1)
= -1 + 3(54)
= -1 + 162
= 161
Which is our answer.
