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( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============= \n" ); document.write( " \n" ); document.write( " |
