Answer:
Ln or an = 3n - 16
Step-by-step explanation:
This is an arithmetic series. You are adding 4 to get the next term.
Ln = a + (n - 1)d
Ln is the last term or the nth term.
a = - 13
d = 3
Solution
Ln = - 13 + (n - 1)3 Remove the brackets
Ln = - 13 + 3n - 3 Combine like terms
Ln = -16 + 3n or
Ln = 3n - 16
