Suppose you want to estimate the proportion of traditional college students on your campus who own their own car. you have no preconceived idea of what that proportion might be. what sample size is needed if you wish to be 9898% confident that your estimate is within 0.030.03 of the true proportion?

hello from mrbilldoesmath!

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
