Question

Which row of pascal's triangle has elements whose sum is 16?

• A. Third row
• B. Fourth row
• C. Fifth row
• D. Sixth row

Answer 1

The correct option is C Fifth row

Elements of the third row = 1, 2, 1
Sum = 4

Elements of the fourth row = 1, 3, 3, 1
Sum = 8

Elements of the third row = 1, 4, 6, 4, 1
Sum = 16

Elements of the third row = 1, 5, 10, 10, 5, 1
Sum = 32

So, the third row of pascal triangle has elements whose sum is 16.
