In the study of sequences, given a number n, the position to term rule tells you how the nth term of the sequence is calculated.
(n*n)+n
n^3 (n cubed)
Oh honey, that's just n times n minus n. So, n squared minus n is just n times (n-1). Hope that clears things up for ya, darling.
That would be -n. Note that if n is positive, -n is negative, whereas if n is negative, -n will be positive.
