Web1 Answer. Sorted by: 2. Obviously the set is bounded below by 0, so inf ( S) ≥ 0. Assume inf ( S) := ε > 0. Then by the Archimedean property of the naturals (i.e. since the naturals are not bounded above), we can find a natural N s.t. 1 / N < ε, but then inf ( S) ≤ inf ( { 1 / N }) < inf ( S), a contradiction. Share. WebThus, 8 n−7n−1 is a multiple of 49 for n≥2 and 0 for n=1. Hence, X consists of all positive integral multiples of 49 of the form 49K n, where K n= nC 2+7. nC 3+...+7 n−2. nC n together with zero. Also, Y consists of all positive integral multiples of 49 including zero. Therefore X⊂Y Hence (A) is the correct answer. Was this answer helpful? 0 0
Web∴ 8 n − 7n − 1 is a multiple of 49 for n ≥ 2 For n = 1, 8 n − 7n − 1 = 8 − 7 − 1 = 0; For n = 2, 8 n − 7n − 1 = 64 − 14 − 1 = 49 ∴ 8 n − 7n − 1 is a multiple of 49 for all n ∈ N. ∴ X contains elements which are multiples of 49 and clearly Y contains all multiples of 49. ∴ X ⊆ Y.

Your understanding is correct, with the following remark. For ∃ x ∀ y: p ( x, y), your phrasing is not consistent. Sometimes you say 'there can be only one', but in other cases 'there is one value'.
