How would I go about showing that the set {5n | n = 1,2,...} is equivalent to ℤ.
I previously attempted to define a function f as f(n) = 5n/2 , when n is even AND (-1)[(5n-1)/(2)] , when n is odd. I then went on to show that the chosen function is 1-1 and onto, but my professor said this was inaccurate.
Any help would be appreciated! Thank you.
