Learn about the nth term in a sequence and how to calculate it. Find the n th term for this sequence: 1, 4, 7, 10... Here n = position and s = term. Eg when n = 2 (2nd position), s = 4. First...

The nth term is a formula that enables us to find any term in a sequence. It refers to the position of a term in a sequence. For example, the first term has n=1, the second term has n=2, the 10th term has n=10 and so on.

2021年7月1日 · The formula to find the nth term of an arithmetic sequence is a n = a 1 + (n-1)d, where a n is the nth term, a 1 is the 1st term, n is the term number and d is the common difference. To find the formula for the nth term, we need a 1 and d.

This calculator can be used to determine the expression for the nth term in a given sequence. Additionally, it will tell you whether the sequence is arithmetic, geometric, quadratic or neither of these.

The nth term of an arithmetic sequence is found using the value of the common difference, the position of the term, and the value of the first term. We subtract 1 from the term position and multiply by the common difference. Then, we add the value of the first term to find the nth term.

Learn about and revise how to continue sequences and find the nth term of linear and quadratic sequences with GCSE Bitesize Edexcel Maths.

The formula for the nth term of an arithmetic sequence is: a n = a 1 + (n-1)d, where a 1 is the first term, d is the common difference and a n is the nth term of the sequence. The following diagrams give an arithmetic sequence and the formula to find the n th term.

2024年10月16日 · Before doing the very formal process to find the n th term, try comparing the sequence to the square numbers 1, 4, 9, 16, 25, … and see if you can spot the formula. For example: Sequence 4, 7, 12, 19, 28, … Square Numbers 1 4 9 16 25
