Homework Statement
Prove that 139/159 is not an upper bound for the set of real numbers:
E ={(14n + 11)/(16n + 19): n ε N}
Homework Equations
The Attempt at a Solution
Right so I let 14n + 11 = 139 and I got n=9.14. Since n is supposed to be natural and the answer I got for n isn't, can I deduce that 139/159 is not an upper bound for E?
