calculus - Is this series sumlimitsin=0nftyfrac1+sinn10n divergent or convergent?

I've been stuck with this problem for a couple of days trying to solve it but got no where till now. The problem states that we have to prove if the series given below is convergent or divergent, if possible use the limit comparison test.




n=01+sinn10n




I'm honestly stuck with this, I managed to pass the limit comparison test by assuming bn=n10n but then stuck with trying to find if the series bn is convergent. Can someone please help me out? Thanks!
