=1+0= 1 :)
This got my excited, my reaction: 'aww thats soooo cute'. So in out 5 minute break in the lesson I tried to figure out the nth term for the sequence of happy numbers (1, 10, 19, 28, 37, 46, 55, 64, 73, 82, 91, 100):
difference is 9 therefore: 9n
so the second term 9*2=18 which doesn't work, so we have to take away 8.
So the nth term is 9n-8.
I decided I might have a look on google to see what others had discovered with these cute little happy numbers. I find this: http://en.wikipedia.org/wiki/Happy_number.
This tells us that a happy number is the square of each digit added together thus:
72 = 49
42 + 92 = 97
92 + 72 = 130
12 + 32 + 02 = 10
12 + 02 = 1.
This somehow does not satisfy me as much :(
Life is like this situation: its great until someone tells you your wrong.
My bubble has burst, lets wait and see whether I find something enjoyable in Math tomorrow, I do hope so!
