Question

the first number of a sequence is 200. every number of the sequence after the first is 100 less than twice the preceding number. what is the 5th number of the sequence

Answer 1

I'll get you started.

200, 300, 500

Take it from there.

Answer 2

how is it 200, 300 when it says it is 100 less than twice the preceding number... isnt it 200-100=100x2==200 again? im confused

Answer 3

100 less than _twice_ the preceeding number.

(200)*2 -100 = 300
(300)*2 -100 = 500
(500)*2 -100 = ... et cetera
