Finite arithmetic series Sequences and series

arithmetic sequence  Given the first term and the common difference of an arithmetic sequence find the recursive formula and the three terms in the sequence after the last one Finding the number of terms in an arithmetic sequence might sound like a complex task, but it's actually pretty straightforward

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, … Arithmetic Sequence A sound understanding of the Arithmetic Sequence is essential to ensure exam success Study at Advanced Higher Maths level will provide

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  Learn how to write an arithmetic sequence in general terms, using a common difference d and a
