Answer:

  1.  b. The common difference is 0.39

  2.  no good answer (Zach's method is exponential; Victoria's is linear)

Step-by-step explanation:

1. The differences in mileage are ...

  24.39 -24 = 0.39

  24.78 -24.39 = 0.39

  25.17 -24.78 = 0.39

The common difference is 0.39.

____

2. Zach's monthly times are ...

  10, 20, 40, 80

The differences are ...

  10, 20, 40

The ratios are ...

  20/10 = 40/20 = 80/40 = 2

Zach's times have a common ratio, so are exponential.

__

Victoria's monthly times are ...

  35, 50, 65, 80

The differences are ...

  15, 15, 15

Victoria's times have a common difference, so are linear.

__

The choices are ...

  a. both exponential; common factor . . . . correct for Zach; not for Victoria

  b. Zach's is linear (has equal factor) . . . incorrect

  c. both exponential; common difference . . . incorrect

  d. Victoria's is linear . . . . correct for Victoria

Choice D describes Victoria's method. Choice A is correct regarding Zach's method, but incorrect regarding Victoria's.

Choices B and C are not self-consistent, so are incorrect on their face.

There is no good choice.
