Plz help with this
Fill in the blanks to make the equation true (Each blank should contain a positive integer.)
\binom{n}{k} = \binom{n - 2}{k} + \binom{n - 2}{k - 1} + \binom{n - 1}{k} + \binom{n - 1}{k - 1} + \binom{n}{k - 1} + \binom{n}{k + 1}
+163 (nk)=(n−2k)+(n−2k−1)+(n−1k)+(n−1k−1)+(nk−1)+(nk+1)
Try using pascal's Identity which states that (nk)=(n−1k)+(n−1k−1)

hopefully this helps :)
