Question

Which series will converge?

Answer 1

first one will for sure

Answer 2

not the second because \(n^2\) gets bigger and bigger

Answer 3

if the third one is supposed to be \(\sum\left(\frac{1}{2}\right)^n\) then that will converge because \(\frac{1}{2}<1\)

Answer 4

and the last one will not converge because it is the same as the second one

Answer 5

so, most likely A then is the best choice ?
