Do you mean to say you can't do 2 and 4?? What are the possible values for n? Do you know what an nth partial sum is?ertagon2 said:
To solve math sequences and series, you can use various methods such as finding the common difference or ratio, using formulas, or using algebraic equations. It is important to carefully analyze the given sequence or series and determine the appropriate method to use.
A sequence is a list of numbers that follow a pattern, while a series is the sum of all the terms in a sequence. In other words, a series is the result of adding up all the terms in a sequence.
The formula for finding the sum of an arithmetic series is Sn = n/2[2a + (n-1)d], where Sn is the sum, n is the number of terms, a is the first term, and d is the common difference.
A sequence or series is convergent if its terms approach a finite limit as the number of terms increases. It is divergent if its terms do not approach a limit or if the limit is infinite. Convergence and divergence can be determined by analyzing the behavior of the terms in a sequence or series.
While a calculator can be a helpful tool in solving math sequences and series, it is important to understand the concepts and methods behind solving them. Relying solely on a calculator may not lead to a complete understanding of the problem and its solution.
