Question

To show that arithmetic sequence formulas have the same structure as linear functions, choose the linear function equation that has the same structure as the arithmetic sequence dn = 6+ (n -1) - 8. (1 point)

Oy=8x+ 6

O y=2x - 8

Answer 1

I’m not sure how to read the given formula — it looks like some multiplication signs might be missing. Could you confirm the arithmetic-sequence formula exactly? (Is it 6 + (n−1)·8, or 6 + (n−1)·(−8), or 6 + (n−1) − 8, etc.?)

Quick note on how to match them: an arithmetic sequence a + (n−1)d corresponds to the linear function y = d·x + (a−d). So pick the linear option whose slope equals the sequence common difference d.
