The question
Question: what comes next?
2, 4, 8, 16, □.
2, 4, 8, 16, □
1 Find the jumps
2 Find the rule
Every jump is the same: ×2.
The rule is: double it each time.
= Rule: double it each time
3 Use the rule
The number before the box is 16.
Double 16 is 16 + 16 = 32.
16 + 16 = 32
So the next number is 32.
= 2, 4, 8, 16, 32
4 Check
16 and 16 make 32.
Yes!
It works.
16 + 16 = 32
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.
