question

A cubic sequence is a sequence of integers given by an=n3+bn2+cn+da_{n}=n^{3}+b n^{2}+c n+d, where b,cb, c and dd are integer constants and nn ranges over all integers, including negative integers. Determine the possible values of a2015⋅a2016a_{2015} \cdot a_{2016} for a cubic sequence satisfying the condition in part (a).
Plain-text mathematical notation (without MathML)
