In this activity, we will fill in the missing numbers in the given sequences.
Example
Fill in the missing numbers in this sequence.
? | 28 | 39 | 50 | ? |
Answer
Look for clues from neighbouring terms to work out the rule.
Here 50 - 39 and 39 - 28 both equal 11.
This means that the rule for the sequence is that each term goes up by 11.
The first term will be 28 - 11 = 17
The last term will be 50 + 11 = 61
17 | 28 | 39 | 50 | 61 |
