Use the graph below to determine a1 and d for the sequence.

graphed sequence showing point 1, 2, point 2, 5, point 3, 8, point 4, 11, point 5, 14, and point 6, 17

a1 = 1; d = 3
a1 = 1; d = −3
a1 = 2; d = 3
a1 = 2; d = −3

A1 would be the first y value, which is 3 and d is the ratio ( distance between each y value) which is 3 ( add 3 to the y value to get the next one)

The answer is a1= 2, d = 3

what grade level is this? need to know so i can look in my old textbooks!
