Answer 1

Answer:

Let

LetA = {n ∈ N | n ≥ 1 and n = 4j − 3 for some j ∈ N}

LetA = {n ∈ N | n ≥ 1 and n = 4j − 3 for some j ∈ N}and

LetA = {n ∈ N | n ≥ 1 and n = 4j − 3 for some j ∈ N}andB = {n ∈ N | n ≥ 0 and n = 2k + 1 for some k ∈ N}.

LetA = {n ∈ N | n ≥ 1 and n = 4j − 3 for some j ∈ N}andB = {n ∈ N | n ≥ 0 and n = 2k + 1 for some k ∈ N}.Prove that A ⊆ B. Here, N = {0, 1, 2, 3, . . . }.

I've tried using some of the set identities but I don't know how to get the answer
