Solve for x. 0.5x = 4.5 Enter your answer in the box. x =

Divide both sides by 0.5

x = 4.5 / 0.5  

x = 9

So x = 9.

Divide both sides by 0.5

x = 4.5 / 0.5  

x = 9

So x = 9.

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

you,

mrb

its c or d   take a lucky guess my dude
