Before I show you how to find the sum of arithmetic series, you need to know what an arithmetic series is or how to recognize it.A series is an expression for the sum of the terms of a sequence. For example, 6 + 9 + 12 + 15 + 18 is a series for it is the expression for ...
Sum of Arithmetic Sequence: The sum of an arithmetic sequence can be obtained using its first and last terms and its number of terms {eq}n {/eq}. That is, the formula for the sum of an arithmetic sequence is: {eq}S_n = \displaystyle \frac{n}{2}(a+l)...
Example 17: The sum of the first n terms of the arithmetic sequence {$$ a _ { n } $$} is $$ S _ { n } $$. The sum of the first n terns of the arithmetic sequence |$$ b _ { n } $$} is $$ T _ { n } $$. Find a$$ \frac { a _ { 6 } } { b _ { 6 ...
