The one that doesn’t go through the origin
If you can find an explicit formula for a sequence, you will be able to quickly and easily find any term in the sequence simply by replacing n with the number of the term you seek. An explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location).
64-16x+x^2 i had this same question and that’s the answer i put and for it right :)
