\n" ); document.write( "\n" ); document.write( "The sum of a series of numbers is calculated by adding the first one to the last one, multiplying by the number of numbers, and then dividing by 2.\r

\n" ); document.write( "\n" ); document.write( "For the series 50 to 151, there are 102 numbers (151 - 50 + 1). Since there is an even number of consecutive numbers, exactly half of

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For the sum of the even numbers, the first is 50 and the last is 150, so the sum is (50 + 150) times 51 and the whole thing divided by 2.\r
