1. common differece, d = a2 - a1d = -8 - 9 = -17d = -25 - (-8) = -17
2. first is solve the common differece,dd = 10.5 - 13 = -2.5so an = 15.5 - 2.5n is the answer
3. a(x) = 440 + 65xwhere x is the number of weeksa(25) = 440 + 65(25)a(25) = $2065

Your company is hosting a benefit 5 kilometer race. How long will the race be to the nearest tenth of a mile?

Morgarella [4.7K]

If you convert the numbers without rounding first, the number would be 3.10686.
So you have to round to the nearest tenth, which should be 3.1 miles.
hope this helped!
