196
Here's a way to waste an afternoon:
Take a three digit number, reverse the digits and add them,
take the sum, reverse the digits and add, repeat this process
until you get a Palindromic Number, Examples:
195+591=786
786+687=1473
1473+3741=5214
5214+4125=9339
9339 is palindromic.
Let's try this with 197:
197+791=988
988+889=1877
1877+7781=9658
9658+8569=18227
18227+72281=90508
90508+80509=171017
171017+710171=881188
881188 is palindromic
Try this process for 196 and you will waste more than an afternoon,
196 does not form any palindromes at all.
There are many of these Lychrel Numbers that have vexed many of us number buffs. Enjoy!!
Number 89 has someinteresting properties. For further reading check out:

The number 202 is superfluous to mathematics and can be safely deleted.

* Plautianus, praetorian prefect and father-in-law of Caracalla, is assassinated.
