Question

Which type of sequence is shown?

-2, 0, 2, 4, 6, . . .

A.
arithmetic
B.
geometric
C.
both arithmetic and geometric
D.
neither arithmetic nor geometric

Answer 1

This would be an Arithmetic Sequence as this pattern would be considered a linear one, how?

We add a constant of two every time we add another term. Geometric would be implying that would be multiplying and or dividing our terms, which would not make sense.

Answer 2

Answer: Arithmetic

Reason: The terms increase by 2 each time. This is the common difference.

The nth term of this arithmetic sequence is -4+2n where n starts at n = 1 and n is an integer.
