Substitute n, the number in the sequence, into the formula.


\n" ); document.write( "The 4th place, n=4, is 4(5)/2 = 10.

\n" ); document.write( "5th place, n=5, is 5(6)/2 = 15.

\n" ); document.write( "6th place, n=6, is 6(7)/2 = 21.

\n" ); document.write( "7th place, n=7, is 7(8)/2 = 28.

\n" ); document.write( "8th place, n=8, is 8(9)/2 = 36.

\n" ); document.write( "
