You can put this solution on YOUR website!
If n = how many consecutive terms starting at n=1, then the summation for the consecutive integers is $\"%28n%2F2%29%28First%2BLast%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your first summation is 79 terms, and your second summation is 61 terms.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice, your question is \"what is the average of x and y\"? As asked, that means to find $\"%28x%2By%29%2F2\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=%2879%2F2%29%281%2B79%29\"$ ; and $\"y=%2861%2F2%29%2880%2B15%29\"$ .\r
\n" ); document.write( "
