Which of the following is an arithmetic sequence?

1/2, 2, 7/2, 5

The differences between adjacent terms of an arithmetic sequence are the same.

No sequence in which signs alternate can be an arithmetic sequence. This eliminates the 1st and 4th choices.

The denominators of the 2nd sequence are an arithmetic sequence, meaning that sequence is a "harmonic" sequence, not an arithmetic one. The differences between adjacent terms get smaller and smaller. They are not a constant.

Differences between terms of the 3rd sequence are all 3/2. This is your arithmetic sequence.

your answer is C: 1/2, 2, 7/2, 5...

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
