Find the missing number that should come at the place of question mark (?). 
The rule is applied column-wise. If the top number is \(n\):
Middle \(= n(n-1)\), and Bottom \(= n(n+1)\).
Check Column 1 (top \(17\)): \(17\times16=272\) (middle) and \(17\times18=306\) (bottom).
Check Column 3 (top \(19\)): \(19\times18=342\) and \(19\times20=380\).
So for Column 2 (top \(13\)): bottom \(=13\times14=182\).
\(\boxed{182}\)
Funky Pizzeria was required to supply Pizzas to three different parties. The total number of pizzas it had to deliver was 800, 70% of which was to be delivered to Party 3 and the rest equally divided between Party 1 and Party 2. Pizzas could be of Thin Crust (T) or Deep Dish (D) variety and come in either Normal Cheese (NC) or Extra Cheese (EC) versions. Hence, there are 4 types of pizzas: T-NC, T-EC, D-NC, D-EC. Partial information about proportions of T and NC pizzas ordered by the three parties are given below.
