How Floyd's Traingle is Calculated?

Solution

To generate first five rows, write down the given values form 1 to ..n depend on row count.

Substitute the values in given Formula Sum Row(n)=n(n²+1)/2

Step 1:

Substitute the first value 1 in the formula Sum Row(1)=1(1²+1)/2 Sum Row(1)=1

Step 2:

Substitute the Second value 2 in the formula Sum Row(2)=2(2²+1)/2 Sum Row(2)=10 / 2 Sum Row(2)=5

Step 3:

Substitute the values in the formula upto n th Row...
