Question

Find A U B if A = {x : x = 2n + 1, n ≤ 5, n ε N} and B = {x : x = 3n – 2, n ≤ 4, n ε N}.​

Answer 1

Answer:

Thus A U B = {1,2,3,4,5,7,10}

Step-by-step explanation:

A: n=1,2,3,4,5

so x=2n+1

so x={3,5,7,9,11}

B: n=1,2,3,4

y=3n-2

B={1,4,7,10}

So A U B = { 1.2,3,4,5 } U { 1,4,7,10}

By defination A U B is a set which is having all the elements which are in

A and B and no element is to be repeated

Thus A U B = {1,2,3,4,5,7,10}
