limit as n approaches infinity for the function ((1)^n)((5n+7)/(6n+5))

multiply both numerator and denominator by 1/n
then
Lim (1)^n (5+7/n)/(6+5/n)
so as n gets large, the second part becomes (5/6)
the first part is +1, depending if n is odd or even.
there is not a limit. however, the funcion is + 5/6 and is bounded by those two numbers.
