Coded Triangle Numbers
Problem 42
The nth term of the sequence of triangle numbers are given by, TN =? n (n+1); So the first ten triangle numbers is:

1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...

By converting a word to a number corresponding to its alphabetical position and adding these values we form A word value. For example, the word value for SKY is + one + + = = T10. If the word value is a triangle number then we shall call the word a triangle word.
