1/(2n+3)>1/(2n+5) smaller denominator bigger fraction
A sequence is increasing if an < an+1 and decreasing if an > an+1 is what i believe is correct, if not please correct me
With this problem an = 1/(2n+3) , (n is a subscript on the left and not the right.)
I checked it by doing:
1/(2n+3) 1/(2(n+1)+2)
1/(2n+3) < 1/(2n+5)
In this shouldn't this be a increasing? But the answer is indeed decreasing? Am i missing something? Thanks in advance for your help.
