The krane children were born two years apart when Michael, the youngest of the six krane chldren was 1 year old.
\n" ); document.write( " The sum of the their ages of all the children was 1+3+5+7+9+11 or 36, a perfect square.
\n" ); document.write( " how many years old was Michael the next time the sum of the children's ages was a perfect square?
\n" ); document.write( ":
\n" ); document.write( "Note that 36/3 = 12
\n" ); document.write( "1 + 11 = 12
\n" ); document.write( "3 + 9 = 12
\n" ); document.write( "5 + 7 = 12
\n" ); document.write( ":
\n" ); document.write( "Using that knowledge find the next square that is even, and can be evenly divided by 3
\n" ); document.write( "not 49
\n" ); document.write( "not 64
\n" ); document.write( "not 81
\n" ); document.write( "not 100
\n" ); document.write( "not 121
\n" ); document.write( "try 144
\n" ); document.write( "144/3 = 48

\n" ); document.write( "Micheal is 19
\n" ); document.write( "19 + 21 + 23 + 25 + 27 + 29 = 144 is the next perfect square
