If you see the pattern it's like

A * B = (A * B) - (A - 1)

For example

6 * 3 = (6 * 3) - (6 - 1) = 18 - 5 = 13

So the missing number will be calculated as,

19 * 11 = (19 * 11) - (19-1) = 209 - 18 = 191

So the missing number is 191
0

I think the missing no:is.........................................191
1 5 1
