Consider an arithmetic series has 14 terms, with t 1 = -100 and t 14 = -48.
\n" ); document.write( "a. Find a formula for the series in sigma notation.
\n" ); document.write( "b. Find the value of S14
\n" ); document.write( "----------
\n" ); document.write( "S(n) = (n/2)[t(1)+t(n)]
\n" ); document.write( "-------
\n" ); document.write( "S(14) = (14/2)[-100-48]
\n" ); document.write( "=7[-148]
\n" ); document.write( "=-1036
