Question

use sigma notation to write the sum:

(3/1+1)+(3/1+2)+(3/1+3)...+(3/1+14).

Answer 1

i am going to guess that this is
\[\frac{3}{1+1}+\frac{3}{1+2}+\frac{3}{1+3}+...\frac{3}{1+14}\]

Answer 2

in which case you could us
\[\sum_{k=1}^{14}\frac{3}{1+k}\] for example

Answer 3

or even
\[3\sum_{k=1}^{14}\frac{1}{1+k}\]

Answer 4

yes! Thank you !!! on my choices i have this as an option...

Answer 5

\[\sum_{j-1}^{14} 3\div1+j\]

Answer 6

3/(1+j)

Answer 7

would that still be correct?
