Question

Tell whether the sequence is arithmetic. If it is, identify the common difference. (-3,-7, -10, -14....)

Answer 1

Not arithmetic.

Explanation:

Lets work out the differences between the terms:

-7 - (-3) = -7+3 = -4

-10 - (-7) = -10 + 7 = -3

-14 - (-10) = -14 + 10 = -4.

So there is NO common difference.

Answer 2

not arithmetic so no common difference
