Answer 1

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

Answer 2

The nth term is 3n -16
