Question

write the summation without sigma notation. then evaluate them.

will be drawn inside!

@hartnn @larryboxaplenty did i do it right? :/

Answer 1

so would i get this?

1-1/1 = 0

2-1/2 = 1/2

3-1/2 = 2/2 = 1 ?


so 0 + 1/2 + 1 ?

Answer 2

and then you evaluate and get 1.5 ?

Answer 3

You should get 1.16, with the 6 repeating = 7/6

Answer 4

oh :/

darn so i did it wrong hahaa

Answer 5

(1-1)/1 = 0/1 = 0
(2-1)/2 = 1/2 = 0.5
(3-1)/3 = 2/3

0+0.5+(2/3) = 1.16 repeating = 7/6

Answer 6

You were right, until the 3rd term. You divided by 2 instead of 3

Answer 7

ahh okay i see :P

so because you get basically 3/6 + 4/6 = 7/6

so 7/6 would be the final answer?

and it would be 0+ 1/2 + 2/3 ?

Answer 8

Yes, (1/2) = 3/6
and (2/3) = 4/6

Answer 9

ahh okay awesome! thank you! :D
