What is the common difference in the sequence 8, 16, 24, 32 ... ?

Subtract any term from the following term.

16 - 8 = 8

24 - 16 = 8

32 - 24 = 8

You don't need to do all the above subtractions. All you need to do is one of them. As you can see, all give the same result, 8.

Answer: The common difference is 8.

To find the common difference in the sequence 8, 16, 24, 32 ... we must find what the difference between two consecutive terms is. A simple way to do this is to find the difference between the first term and the second term. That means that we have to do the second term - the first term. That means we do 16 - 8 which gives us that the common difference is 8.
