Question

Consider the sequence 16, –8, 4, –2, 1, ...
a. Describe the pattern formed in the sequence.
b. Find the next three terms.

Answer 1

Divide by -2

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

is a geometric sequence
mutiply by T2/T1

Answer 6

ok i get it thanks

Answer 7

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?
