![]() If we represented an arithmetic sequence on a graph it would form a straight line as it goes up (or down) by the same amount each time. Here are some examples of arithmetic sequences:Īrithmetic sequences are also known as linear sequences. The term-to-term rule tells us how we get from one term to the next. If we add or subtract by the same number each time to make the sequence, it is an arithmetic sequence. The difference between consecutive terms is an arithmetic sequence is always the same. doi: 10.1511/2006.59.200.An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term.įor example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6.Īn arithmetic sequence can be known as an arithmetic progression.
