WebFeb 12, 2003 · 21. For the proof, we will count the number of dots in T (n) but, instead of summing the numbers 1, 2, 3, etc up to n we will find the total using only one multiplication and one division! To do this, we will fit two copies of a triangle of dots together, one red and an upside-down copy in green. E.g. T (4)=1+2+3+4.
