wheres the answer

Step-by-step explanation:  3.87 divided by 3 = 1.29

                                              3.32 divided by 2 = 1.66

                                              1.66 - 1.29 = 0.37

  you'll save more if get the 3 for 3.87 because you will save 37 cents

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
