Answer: Xn = n(n+1)/2
Step-by-step explanation:
Firstly, you work with asingle dot for each and let n= 1,2,3,4....
Now if you double the dots, it will form a rectangle and it is easier to work with many dots i.e just multiple n by n+1
Dots in rectangle= n(n+1)
But remember the number of dots were doubled therefore,
Dots in triangle = n(n+1)/2.
