Example Question #1 : How To Find The Common Difference In Sequences
What number comes next in the sequence?
_______
In order to find the next number in the sequence, take a look at the patterns and common differences between the existing numbers in the sequence. Starting with , we add to get , subtract to get , and then repeat.
When we get to for the second time in the sequence, we are adding to get . By the next step in the sequence, we will subtract to get the missing number .
Example Question #1 : How To Find The Common Difference In Sequences
What is the next number in the sequence?
_______
In order to find the next number in the sequence, take a look at the patterns and common differences between the existing numbers in the sequence. Starting with , we add to get and then subtract to get .
By the time we get to , we have subtracted from to complete the cycle of common differences. We will therefore add to next, getting the missing number .
Example Question #3 : How To Find The Common Difference In Sequences
What is the next number in the sequence?
_______
In order to find the next number in the sequence, take a look at the patterns and common differences between the existing numbers in the sequence. Starting at the beginning, we multiply by to get and then divide by to get .
We multiply the second in the sequence by to get , so by the logic of the sequence we will be dividing by to get the missing number .
