It looks hard but its not!
Say I had a formula like:
2n-1
Quick definition of N
N is the number of the number in the sequence.
E.G: Here is a sequence:
10,19,28,37,46,55
10 is the 1st number in the sequence so therefore it's N is 1
19 is the 2nd number in the sequence so therefore it's N is 2
So back to our problem!
If you wanted to find the 1st number then you would do 2x1-1 which is 1
So if you add 2 onto the number you will get the second number in the sequence!
The Nth term is an easy concept but it is hard to explain I hope I have helped you!

To find the nth term of a sequence, we first need to identify the pattern or rule governing the sequence. In this case, the sequence appears to be increasing by 4, then 8, then 12, then 16, and so on. This pattern suggests that the nth term can be represented by the formula n^2 + n, where n is the position of the term in the sequence. So, the nth term for the given sequence is n^2 + n.
If the sequence is non-linear, you need to establish how it is defined.
The nth term in the sequence -5, -7, -9, -11, -13 can be represented by the formula a_n = -2n - 3, where n is the position of the term in the sequence. In this case, the common difference between each term is -2, indicating a linear sequence. By substituting the position n into the formula, you can find the value of the nth term in the sequence.
Three or more terms of a sequence are needed in order to find its nth term.
