Question 1088942

-8,-6,-4,-2

The recursive rule is a<sub>n</sub> = a<sub>n-1</sub> + 2, a<sub>1</sub> = -8.

The general term is

a<sub>n</sub> = a<sub>1</sub> + (n-1)d

The common difference is 2, so d=2

a<sub>n</sub> = -8 + (n-1)(2)
a<sub>n</sub> = -8 + 2(n-1)
a<sub>n</sub> = -8 + 2n-2
a<sub>n</sub> = 2n-10
a<sub>12</sub> = 2(12)-10 = 24-10 = 14

Checking:

-8,-6,-4,-2,0,2,4,6,8,10,12,14
