Step by step
The question
Question: what comes next?
11, 12, 13, □.
11, 12, 13, □
1 Find the jumps
2 Find the rule
Every jump is the same: +1.
The rule is: add 1 each time.
= Rule: add 1 each time
3 Use the rule
The number before the box is 13.
13 + 1 = 14.
13 + 1 = 14
So the next number is 14.
= 11, 12, 13, 14
4 Check
We go one jump back.
14 − 1 is 13.
Yes!
It works.
14 − 1 = 13
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.
Answer
= 11, 12, 13, 14
