Write an equation for the n th term of the arithmetic sequence then find a10 -6,-9,-12,-15

= -33

Step-by-step explanation:

-6, -9, -12, -15

The common difference is -3

d = common difference

Arithmetic sequence formula:

= + (n - 1) d

= -6 + (10 - 1) -3

= -6 + 9 × -3

= -6 - 27

= -33

the answer is c)8

step-by-step explanaction:

answer is x<
