25 − 15 = 10.1 a + 1 b + c = 1 4 a + 2 b + c = 4 9 a + 3 b + c = 8 then the formula for this sequence is ( 1 / 2 ) n2 + ( 3 / 2 ) n − 1.This constant is called a common difference.Then write out the sequence of differences of that sequence:The sequence below is another example of an arithmetic sequence.

Suppose you have a list of terms that decreases, such as ….To find the common difference, simply subtract the first term from the second term, or the second from the third, or so on.Similarities and differences goal suggestions.Watch this one minute video for a quick example of how to find the common difference:The key thing here (which is why i keep repeating it!) is that it's easy to add fractions if they're written in terms of the same common denominator.
