No. of children in first row = 3 children
No. of children in second row = 7 = 3 + 4 = 7 children
No. of children in third row = 11 = 7 + 4 = 11 children
No. of children in fourth row = 15 = 11 + 4 = 15 children
A.T.Q
4 children are increasing in every row
So , No .of children in fifth row = 15 + 4 = 19 children
☆ No. of children in sixth row = 19 + 4 = 23 children
I Hope My answer is correct
