Web5 feb. 2010 · n² = 1 4 9 16 25. n²+1 = 2 5 10 17 26. This is the required sequence, so the nth term is n² + 1. There is no easy way of working out the nth term of a sequence, other than to try different possibilities. Tips: if the sequence is going up in threes (e.g. 3, 6, 9, 12...), there will probably be a three in the formula, etc. WebTo find the nth term, first calculate the common difference, d . Next multiply each term number of the sequence (n = 1, 2, 3, …) by the common difference. Then add or subtract …

Finding the nth term rule of a quadratic sequence: The nth term rule of a quadratic sequence can always be written in the form an2 + bn + c. WebStep 1: First we must find the n^ {th} nth term of the sequence of the sequence as before, this gives. 4n-7 4n − 7. Step 2: Next we need to write the n^ {th} nth term as an euqation equal to 1143 1143 and solve for n n. If n n solves to give an integer, then 1143 1143 is part of the sequence.
