Re: Numbers in a Triangle: Curious Question
Let me also clarify that you should take the greatest integer value if the number is closest to the first integer greater than x . Otherwise you use the least integer value function which is the greatest integer less than the value x .
Or, just round the number to the closest positive integer .
[sqrt(11*2)]=5 which is the 5th row .
[sqrt(10*2)] =4 which is the 4th row .
