look at this series 2,1,1/2,1/4

what number should come next?

try to find how much it is going down or finding the rule what do you think the rule is?

Good job, meow. This is actual helping -- you're explaining HOW to get to the answer instead of just handing it out!

Congrats!

good start, but "how much" is an ambiguous term.

To determine the next number in the series 2, 1, 1/2, 1/4, we need to find the pattern or rule that governs the sequence. In this case, it appears that each term in the series is obtained by dividing the previous term by 2.

For example:
- 2 ÷ 2 = 1
- 1 ÷ 2 = 1/2
- 1/2 ÷ 2 = 1/4

Following this pattern, the next number in the series would be obtained by dividing 1/4 by 2:

1/4 ÷ 2 = 1/8

Therefore, the next number in the series is 1/8.
