The missing number is 10.

 

In Pascal's Triangle, each number (except for the 1s on the edges of each row) is the sum of the two numbers directly above it in the previous row.

 

For the sixth row where the missing number is located, we look at the fifth row which consists of the numbers 1, 4, 6, 4, 1.

 

The number we are trying to find in the sixth row has the two numbers 6 and 4 directly above it from the fifth row. When we add 6 and 4 together (6 + 4), we get 10.

 

So the completed Pascal's Triangle would be:
