\[\sum_{k=1}^{4} (k+2)\]

Answer 4

\[(k+2)^{2}\]

Answer 5

\[\sum_{k=1}^4(k+2)^2\]??

Answer 6

put \(k=1\) get \((1+2)^2=3^2=9\)
put \(k=2\) get \((2+2)^2=4^2=16\) etc
then add up the four numbers

Answer 7

Yes thats correct

Answer 8

i.e. add up \(9+16+25+36\)

Answer 9

so you keep going like k=3 and k=4 and then those four numbers added together is the answer?
