(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Is this statement correct?

If the nth term of a sequence is a quadratic expression in n, then the sequence is an A.P.

2. Relevant equations

3. The attempt at a solution

Take arbitrary t(n)=n^2-2n-2

I substituted 1,2,3 in the above expression and noted the c.d.

It is not constant.

But the book says that this statement is correct.

Any ideas?
