Hola, iam Helen Frank, Have a happy day.
What Numbers Make People Happy? [Solved]
Wow! These numbers are pretty cool - 1, 7, 10, 13, 19, 23, 28, 31, 32, 44, 49, 68, 70 79 82 86 91 94 97 100 and so on. They’re called ‘happy numbers’ because their 2-recurring digital invariant sequences have a period of one. Pretty neat!
