Find the limit superior and limit inferior of the following sequences (a) {an}[infinity]n=1 , with an = {( n + 3)/n if n is even (−2)−n if n is odd (b) {bn} [infinity] n=1, with bn = {2n if n is a digit ,1/2n otherwise
n=1 is part of {an}n=1 and the infinity symbol goes to the top of {an}[infinity]
