The sequence is a set of ordered numbers. The number of elements in the sequence can either be finite or infinite. More about Arithmetic Sequence (Arithmetric Progression). An arithmetic sequence is defined as a sequence of numbers with a constant difference between each consecutive term. It is also known as arithmetic progression. Arithmetic Sequnece â a1, a2, a3, a4, â¦, an; where a2 = a1 + d, a3 = a2 + d, and so on.
The following sequences are arithmetic sequences: Sequence A: &nbsp 5, 8, 11, 14, 17, ... Sequence B: &nbsp 26, 31, 36, 41, 46, ... Sequence C: &nbsp 20, 18, 16, 14, 12, ... For sequence A, if we add 3 to the first number we will get the second number.
