Find the nth term of an arithmetic sequence
WebNow it's your turn to find terms of sequences using their recursive formulas. Just as we used a (n) a(n) to represent the n^\text {th} nth term of the sequence 3, 5, 7, ..., we can … WebSince arithmetic and geometric sequences are so nice and regular, they have formulas. For arithmetic sequences, the common difference is d, and the first term a1 is often referred to simply as "a". Since we get the next term by adding the common difference, the value of a2 is just: a2 = a + d. Continuing, the third term is: a3 = ( a + d) + d ...

Did you know?
WebArithmetic sequence formula is: \ (a^n=a^1+ (n-1) d\) ADVERTISEMENT. \ (A^n\) = any nth term in the given sequence. \ (A^1\) = it represents the first term in the given sequenced = it is the common difference that exists among terms. An arithmetic sequence equation can be simplified and found by using this formula. WebFor a geometric sequence, the nth term is calculated using the formula s x s (n - 1). The 5-th term of a sequence starting with 1 and with a ratio of 2, will be: 1 x 2 4 = 16. Calculating the sum of an arithmetic or geometric sequence. The sum of an arithmetic progression from a given starting value to the nth term can be calculated by the formula:
