Step by step
The question
Question: what comes next?
1, 3, 5, 7, □.
1, 3, 5, 7, □
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 7.
7 + 2 = 9.
7 + 2 = 9
So the next number is 9.
= 1, 3, 5, 7, 9
4 Check
We go one jump back.
9 − 2 is 7.
Yes!
It works.
9 − 2 = 7
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.
Answer
= 1, 3, 5, 7, 9
