Question

4.02 Lesson check ! (10)

Answer 1

Yes (choice 1)
d = - 30 (choice 4)

Explanation:

It is an arithmetic sequence because the difference between successive terms is -30

-32 - (-2) = -32 + 2 = -30

-62 - (-32) = -62 + 32 = -30 etc.

Therefore the common difference is -30

Answer 2

yes

d = -30.

the difference between each successive term will give you -30, that's the common difference.

E.g -62 - ( -32) = -62 + 32 = -30
