The second difference is common, which means that the sequence is quadratic. 3. Find the coefficient of the \(n^{2}\) term by dividing the second difference by 2.

A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers ...

This sequence is going up by four each time, so add 4 on to the last term to find the next term in the sequence. \(3, 7, 11, 15, 19, 23, …\) To work out the term to term rule, give the starting ...
