Scientists studying a bacteria sample find that after starting with 120 cells, the number of cells doubles every hour. Which of the following equations is a function that will predict C(h), the number of cells after h hours have passed?

1.C(h) = 120(2)"
2.C(h) = 120 + 2"
3.C(h) = 120(21)
4.C(h) = (120)(2)(h)

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
