4th grade / Pattern / Next number / Subtract a number each time
This topic explores number patterns that involve subtracting the same number each time. This type of sequence of numbers is known as a descending arithmetic sequence because it changes by the same amount each time and gets smaller each time. Let's start by looking at a simple number pattern:
30 , 25 , 20 , 15 , _ , _ ...
What comes next? To find out, let's first look at the differences between each pair of consecutive numbers:
You can see that in each step, we subtract 5 from the previous number to get the next number in the sequence. Now, let's use this rule to find the next number:
15 - 5 = 10
So, the next number in the pattern is 10. The sequence now looks like this:
30 , 25 , 20 , 15 , 10 , _ ...
If we do the next number in the sequence, it will be 10 - 5 which is 5,
30 , 25 , 20 , 15 , 10 , 5 ...
To recap, always remember the following steps when identifying the next number in a pattern that subtracts the same number each time:
This topic asks you to work out the next number in the pattern of numbers created by subtracting the same number each time.
With our Four in a row math game you will be practicing the topic "Subtract a number each time" from 4th grade / Pattern / Next number. The math in this game consists of 16 questions that ask you to pick the next term when subtracting the same number each time.
