The Arithmetic Sequence Whose Nth Term Is 2n 1 Is

The sum of the first n terms s n of an arithmetic sequence is calculated by the following formula.

The arithmetic sequence whose nth term is 2n 1 is. The first term of an arithmetic sequence is equal to frac 5 2 and the common difference is equal to 2. An arithmetic sequence is any list of numbers that differ from one to the next by a constant amount. The main purpose of this calculator is to find expression for the n th term of a given sequence. Find the value of the 20 th term.

You may also be asked. Also it can identify if the sequence is arithmetic or geometric. Learn how to find the nth term of an arithmetic sequence. A sequence is a list of numbers values exhibiting a defined pattern.

For example the list of even numbers is an arithmetic sequence because the difference from one number in the list to the next is always 2. If the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d then the nth term of the sequence is given by. The a p whose nth term is 2n 1 is the sum of the first fifteen terms of the series 5 10 20 is the 7th term of an arithmetic sequence whose first term is 2 and common difference of zero is. The calculator will generate all the work with detailed explanation.
