\"Sum+=+NumberOfTerms%2A%28FirstTerm+%2B+LastTerm%29%2F2\"
\n" ); document.write( "\"342+=+n+%2A%2816%2B60%29%2F2\"
\n" ); document.write( "\"342+=+n%2A76%2F2\"
\n" ); document.write( "\"342+=+38n\"
\n" ); document.write( "\"9+=+n+\"
\n" ); document.write( "Let the difference between each term be x.
\n" ); document.write( "If there are 9 terms, we know that 16+8x = 60 (use one less than 9 )
\n" ); document.write( "so
\n" ); document.write( "\"60+-+16+=+8x\"
\n" ); document.write( "\"44+=+8+x\"
\n" ); document.write( "\"x+=+5.5\"
\n" ); document.write( "
