First we need to find the sum of these 9 consecutive integers.\r
\n" ); document.write( "\n" ); document.write( "If we have some integer X, then (X + 1) will be the next integer, we want 9 integers total so we have:\r
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( "Combining like terms we get:\r
\n" ); document.write( "\n" ); document.write( "\"9X\" plus the sum of (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8). You can either hand calculate this sum or you can use the formula n(n + 1)/2 is the sum of any numbers. So our n in this case is 8 so we have 8 * 9/2 = 36\r
\n" ); document.write( "\n" ); document.write( "So we have
\n" ); document.write( "\"9x+%2B+36+=+180\"
\n" ); document.write( "\"9x+=+144\"
\n" ); document.write( "\"x+=+16\"\r
\n" ); document.write( "\n" ); document.write( "So our 9 terms are:\r
\n" ); document.write( "\n" ); document.write( "16, 17, 18, 19, 20, 21, 22, 23, and 24. The mean is the average which is the middle number which is the mean.\r
\n" ); document.write( "\n" ); document.write( "So mean = 20 = median, mean - median = median - mean = 0 \n" ); document.write( "
\n" );
