Six, squared

36

It's nice being a square number. I think I prefer it to being a round number. Next year I'll be a prime number

Have you noticed that the difference between squares, certainly of low numbers, is more often that not a prime number? 4-1=3; 9-4=5; 16-9 =7; 25-16=9; 36-25=11; 49-36=13; 64-49=15; 81-64=17; 100-81=19.

Thank you to A-listers Scary and Zoe for greetings
