Note that 2014≡−3mod2017. We have for k≥1
(k2014)≡k!(−3)(−4)(−5)....(−2−k)mod2017
≡(−1)k(kk+2)mod2017
Therefore
k=0∑62(k2014)≡k=0∑62(−1)k(2k+2)mod2017
This is simply an alternating series of triangular numbers that goes like this: 1−3+6−10+15−21....
After finding the first few sums of the series, it becomes apparent that
k=1∑n(−1)k(2k+2)≡−(2n+1)(2n+1+1)mod2017 if n is odd
and
k=1∑n(−1)k(2k+2)≡(2n+1)2mod2017 if n is even
Obviously, 62 falls in the second category, so our desired value is
(262+1)2=322=(C) 1024
Sidenote
Another way to finish, using the fact that (2k+2)=1+2+⋯+(k+1):
\begin{align*} \sum \limits_{k=0}^{62}(-1)^k\dbinom{k+2}{2} &\equiv \sum \limits_{k=1}^{63}(-1)^{k-1} (1 + 2 + \dots + k) \\ &\equiv 1 - (1+2) + (1+2+3) - (1+2+3+4) + \dots + (1 + \dots + 63) \\ &\equiv 1 + 3 + 5 + \dots + 63 \\ &\equiv \boxed{1024} \mod 2017 \end{align*}
