when a pattern shows counting on by ten
For example, we assume a pattern counting by 10
10,20,30,40......
If we count by 10 , then the difference between two terms is 10
Counting by 10 means common difference should be 10
In that example , 10,20,30,40......
20 -10 = 10
30 - 20 = 10
40 - 10 = 10
We can see that the common difference is 10
To deduce of a pattern or number sequence shows counting on by 10, we calculate the common difference of the sequence of numbers
- The common difference is the difference between two successive values in a sequence. Hence, if a sequence gives a common difference of 10, then the pattern shows counting on by 10.
- Commom difference, d = n2 - n1
Using an hypothetical sequence ; 10,20,30,40,50,60
The common difference = d2 - d1 = d3 - d2
Common difference = 20 - 10 = 30 - 20 = 10
Since, the common difference of the sequence is 10, then the pattern shows counting on by 10.
