Question

Find the next two terms 400, 200, 100, 50, 25

Answer 1

12.5, 6.25

the sequence is geometric with common ration r =
`(1)/(2)`

r =
`(200)/(400)` =
`(100)/(200)` =
`(1)/(2)`

to find the next term in the sequence multiply the previous term by
`(1)/(2)`

25 ×
`(1)/(2)` = 12.5

12.5 ×
`(1)/(2)` = 6.25

Answer 2

For this sequence, every number is divided by two. 400/2 = 200, 200/2 = 100, etc.

To find the next two terms, you divide 25/2 = 12.5, then 12.5/2 = 6.25

The next two terms are 12.5 and 6.25
