The question
Question: what comes next?
2, 4, 6, 8, □.
2, 4, 6, 8, □
1 Find the jumps
2 Find the rule
Every jump is the same: +2.
The rule is: add 2 each time.
= Rule: add 2 each time
3 Use the rule
The number before the box is 8.
8 + 2 = 10.
8 + 2 = 10
So the next number is 10.
= 2, 4, 6, 8, 10
4 Check
We go one jump back.
10 − 2 is 8.
Yes!
It works.
10 − 2 = 8
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.

The question
Question: what comes next?
3, 7, 11, 15, □.
3, 7, 11, 15, □
1 Find the jumps
2 Find the rule
Every jump is the same: +4.
The rule is: add 4 each time.
= Rule: add 4 each time
3 Use the rule
The number before the box is 15.
15 + 4 = 19.
15 + 4 = 19
So the next number is 19.
= 3, 7, 11, 15, 19
4 Check
We go one jump back.
19 − 4 is 15.
Yes!
It works.
19 − 4 = 15
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.
Answer = 3, 7, 11, 15, 19

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.
