Divide by -2

anonymous · Answer

but i thought you would have 2 take 0.5 and times it?

anonymous · Answer

i mean -0.5 because if you take -0.5 x 16 you get -8 then if i keep doin that it adds out?

anonymous · Answer

16 divided by -2 = -8, -8 divided by -2 = 4, 4 divided by -2 = -2, and so forth.

anonymous · Answer

is a geometric sequence
mutiply by T2/T1

anonymous · Answer

ok i get it thanks

anonymous · Answer

Multiplying by -0.5 and dividing by -2 are the same.  Think of 4 divided by 1/2.  Wouldn't that be the same as 4 X 2, the inverse?
