Answer 1

converges to whatever that sum is

Answer 2

no actually the answer is diverges

Answer 3

its diverges

Answer 4

but if i add that in my calculator it has a sum

Answer 5

=211/80
its simple addition
its not infinite series
there is not a finite amout of terms
so it does converge

Answer 6

i mean there is a finite amount of terms

Answer 7

so i don't understand how you can say this addition with only 5 terms is divergent
is 2+2 divergent
no it is simply 4
2+2 converges to 4
