Video: Arithmetic Sequence

arithmetic sequence  Explanation This formula tells us that, guven an arithmetic sequence, we can find the common difference d by subtracting any term from the next For example, An arithmetic sequence is a sequence in which the same number is added or subtracted from one term to the next Q

If the first term of the sequence is a and the common difference is d, then the arithmetic sequence can be written as a, a+d, a+2d, a+3d, …, a+d, … Key Concepts · An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant · The constant between two consecutive

The formula for the sum of an arithmetic sequence is: S n = n 2 , where: n = the number of terms to be added; a = the first term in the The following sequences are arithmetic sequences: Sequence A: 5 , 8 , 11 , 14 , 17 , For sequence A, if we add 3 to the first number we will get the
