Using arithmetic sequences formulas

arithmetic sequence  This algebra video discusses the math formulas used when dealing with arithmetic sequences Key Concepts A recursive formula for an arithmetic sequence with common difference d d is given by an=an−1+d,n≥2 a n = a n − 1 + d , n ≥ 2 An explicit

The values of the truck in the example are said to form an arithmetic sequence because they change by a constant amount each year  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, …

Learn how to write an arithmetic sequence in general terms, using a common difference d and a In y = ax +b when are a, -ba, b in arithmetic progression The polynomial y = ax^2 + bx + c has roots r1 and r2 Can a, r1, b, r2 and c be in arithmetic
