A recursive sequence is a sequence of numbers where each number, or term, is found by applying some rule to one or more of the previous terms. A formula for the recursive sequence is a formula which shows what that rule is, and sometimes, what the starting term is.Recursive...
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 ...
Median represents the middle value for any group. It is the point at which half the data is more and half the data is less. Median helps to represent a large number of data points with a single data point. Understand how to find median using examples.
A geometric series is a sequence of numbers with each term being a multiple of the previous term. Explore the characteristics of a geometric series, the formula to identify its terms, and examples of using the formula to construct a geometric series. Definitions Let's define a few basic ter...

Refer to the examples of Mean proportion to understand the Right sequence of steps you have to follow to solve a particular problem. Make sure that you know the derivations of a formula or a theorem as they will come in handy while solving a complex question based on Mean proportion. ...
A recurrence relation is a way of describing a sequence of numbers with a recursive formula. One of the best-known recurrence relations is the one that describes the Fibonacci sequence.The Fibonacci sequence is the sequence 0, 1, 1, 2, 3, 5, 8, 13, ... It starts with 0 and 1, an...
