Answer:

- 2

Step-by-step explanation:

Using the term- to - term rule of subtract 5

This means to find a term in the sequence, subtract 5 from the previous term.

Given a(1) = 13, then

a(2) = a(1) - 5 = 13 - 5 = 8

a(3) = a(2) - 5 = 8 - 5 = 3

a(4) = a(3) - 5 = 3 - 5 = - 2

The fourth term is - 2

Answer:

y = 0.5x + 2

Step-by-step explanation:

the y-intercept is 2, as shown in the graph

the slope is 0.5. this is because while the x-value goes up by 2, the y-value goes up by one (from 0, 2 to 2, 3).

using the slope formula of rise / run, you get 1/2, which is equal to 0.5
