Express the given sums using sigma notation for the following:
\n" ); document.write( " a) 2+6+10+14+18:::: SUM[2+(n-1)4] from n = 1 to n = 4
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( " b) 5+25+125+625:::: SUM[5^n] from n = 1 to n = 4
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( " c) 1/2+1/2×3+1/3×4+...+1/99×100:::
\n" ); document.write( "SUM[(1/2) + (1/n)*(n+1)] from n = 1 to n = 99
\n" ); document.write( "=============
