How do you find the common difference between two adjacent terms?
Subtract the previous one from the current one.
What is a sequence in which a common difference separates terms?
arithmetic sequence
What is a sequence where consecutive terms have a common difference?
1 2 3 4 5 6 7 8 9 10 11 12 The common difference between consecutive terms is 1.
What is an common difference?
A common difference is a mathematical concept that appears in arithmetic sequences. An arithmetic sequence is a sequence of numbers, U(1), U(2), ... generated by the following rule: U(1) = a U(2) = U(1) + d U(3) = U(2) + d and, in general, U(n) = U(n-1) + d that is, you have a starting number a and, after that, each term in the sequence is found by adding a fixed number, d, to the previous term in the sequence. An equivalent formulation is U(n) = a + (n-1)*d The difference between any two consecutive terms is d and this is the common difference. For example, in the sequence 3, 7, 11, 15, 19, .... the common difference is 4. This is because 7-3 = 4 11-7 = 4 15-11 = 4 and so on.
