Hi I don't understand the logic in the picture i added. They say that "that sum of the series = the limit of the sequence"
The limit is 2/3 BUT the sum, Ʃ, must be 2*1/(3*1+5) + (2*2/(2*3+5) + 2*3/(2*3+5) ...+
Which is obviously much larger than 2/3 if all the terms are added together?? it's like adding 2/3+2/3+2/3 which is = 6/2 =2??
Is there something I'm misunderstanding here?
