anonymous · Answer

$$\sum_{n-1}^{4}(n+1)$$

anonymous · Answer

should be n+4 not n+1

ranga · Answer

Is it n-1 at the bottom of the sigma symbol or n = 1

anonymous · Answer

it's a minus sign

ranga · Answer

Can you put the picture of the problem up?

anonymous · Answer

I will try.  I have to scan it in to my computer

ranga · Answer

Okay, I will wait for the problem to be posted.

attachment

anonymous · Answer

ok - if n=1 then I would just do 1+4=5, 2+4=6. 3+4-7,4+4=8
then add them together to get 26

anonymous · Answer

Is that correct?

ranga · Answer

I don't see this problem in the posted pic.

ranga · Answer

I think in the problems you have posted it is all "n = " and not "n -"

ranga · Answer

Yes 26 is the correct answer for this problem.

ranga · Answer

All the rest of the problems you do the same way.  Put n = 1, 2, 3, etc. till the upper limit, evaluate the expression and add them all up.
