Question

Explain how the common difference in an arithmetic sequence is like the slope of a linear function.

Answer 1

Arithmetic sequences have a starting number A_sub0 and a common difference, d.

A_sub0 is found when n = 0. The common difference is a_sub2 - a_sub1.
linear functions have a y-intercept and a slope.
The a_sub0 is similar to the y-intercept and the slope is similar to the "common difference".
