General formula for arithmetic sequence
WebArithmetic sequence: a n = a + (n - 1) d, where a = the first term and d = common difference. Geometric sequence: a n = ar n-1, where a = the first term and r = common ratio. Fibonacci sequence: a n+2 = a n+1 + a n. The first two terms are 0 and 1. Square number sequence: a n = n 2. Cube number sequence: a n = n 3. WebIn General we could write an arithmetic sequence like this: {a, a+d, a+2d, a+3d, ... } where: a is the first term, and d is the difference between the terms (called the "common difference") Example: (continued) 1, 4, 7, 10, 13, 16, 19, 22, 25, ... Has: a = 1 (the first term) d = 3 (the "common difference" between terms) And we get:
