Step by step
The question
Question: what comes next?
125, 150, 175, 200, □.
125, 150, 175, 200, □
1 Find the jumps
2 Find the rule
Every jump is the same: +25.
The rule is: add 25 each time.
= Rule: add 25 each time
3 Use the rule
The number before the box is 200.
200 + 25 = 225.
200 + 25 = 225
So the next number is 225.
= 125, 150, 175, 200, 225
4 Check
We go one jump back.
225 − 25 is 200.
Yes!
It works.
225 − 25 = 200
Let's look back.
First: find the jumps.
Then: find the rule.
Then: use the rule.
Last: check.
Answer
= 125, 150, 175, 200, 225
