Use this to show the sequence ( s n ) is increasing, i.e. s n +1 > s n for all n ≥ 1. (d) Prove that the subsequence of even terms is bounded by 4, i.e. ± 1 + 1 2 n ² 2 n ≤ 4 . Do this by plugging a = 1 and b = 1 + 1 2 n into the formula from part (b). Argue that since the sequence is increasing all terms must be bounded by 4. (e) Conclude the sequence converges, and denote its limit by e . (f) Find the limits of ± 1 + 1 2 n ² 2 n , ± 1 + 1 n ² 2 n , and ± 1 + 1 2 n ² n . 1...
