Identify the type of sequence.

4, –4, 4, –4,. . .

2, 2 1/3, 2 2/3, 3, 3 1/3,. . .

1/10, 3/20, 5/30, 7/40,. . .

in steps

Step-by-step explanation:

4, –4, 4, –4,. . .   Geometric with common ratio of -1

2, 2 1/3, 2 2/3, 3, 3 1/3,. . .Arithmetic  with common difference of 1/3

1/10, 3/20, 5/30, 7/40,. . .  neither

first picture(left): geometric, ratio 1/2

2nd picture (right): arithmetic, difference -4

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
