Sum of Arithmetic Sequence Formula

Arithmetic Sequence arithmetic sequence

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same

arithmetic sequence 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 Key Concepts · General Term of an Arithmetic Sequence The general term of an arithmetic sequence with first term {a}_{1} and the common difference d Subtracting the number in the times table from the term results in a constant difference of plus eight between the table and the sequence The 𝒏th term rule

ชื่อ ฟ The nth or general term of an arithmetic sequence is given by an=a1+d So in our example a1=2 and d=4 so an=2+4=2+4n−4=4n−2
