Question

The depth of snow after n hours of a snowstorm is represented by the function f(n + 1) = f(n) + 0.8 where f(0) = 2.5. Which statement describes the sequence of numbers generated by the function?

The depth of snow was 0.8 inches when the storm began, and 2.5 inches after the first hour of the storm.
The depth of snow was 1.7 inches when the storm began, and 0.8 inches of snow fell each hour.
The depth of snow was 2.5 inches when the storm began, and increased by 0.8 inches each hour.
The depth of snow was 3.3 inches when the storm began, and 2.5 inches of snow fell in 1 hour.

Answer 1

"The depth of snow was 2.5 inches when the storm began, and increased by 0.8 inches each hour."

Reason: f(0)=2.5 gives the starting depth, and f(n+1)=f(n)+0.8 means each hour the depth increases by 0.8 inches.
