💎Number sequences
🎇A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequence.
🥏Example: 9 , 15 , 21 , 27, ____
🎇In this example, the difference between each number is 6. So the rule for this sequence is to add 6 each time.
🧨Now you can work out the next number in the sequence: 27 + 6 = 33
Learn with an example
Which number is missing from this sequence?
__, 42, 46, 50, 54, 58, 62
First, look for a pattern. Notice how each number is 4 more than the previous number:
__, 42, 46, 50, 54, 58, 62
To make the pattern complete, the number 38 must go in the blank space.
Which number is missing from this sequence?
94, __, 102, 106, 110
First, look for a pattern. Notice how each number is 4 more than the previous number:
94, __, 102, 106, 110
To make the pattern complete, the number 98 must go in the blank space.
Which number is missing from this sequence?
26, 36, 46, 56, ___
First, look for a pattern. Notice how each number is 10 more than the previous number:
26, 36, 46, 56, __
To make the pattern complete, the number 66 must go in the blank space.
Which number is missing from this sequence?
704, __, 504, 404, 304, 204
First, look for a pattern. Notice how each number is 100 less than the previous number:
704, __, 504, 404, 304, 204
To make the pattern complete, the number 604 must go in the blank space.
Let’s practice!
