The Theosophical Extension of a number is the sum of all integer values from 1 to the object number.

i.e. the theosophical extension of the number 4 is: 1 + 2 + 3 + 4 = 10.

You may alternatively use the formula (n x (n+1))/2.

i.e. (4 x (4 + 1))/2 = (4 x 5)/2 = 20 / 2 = 10.

Enter the number for which you would like the Theosophical Extension:
