Given the universal set {x : xϵN and x < 20}, then find : B = {y : y = 2n + 3, nϵN}.

Solution

U={x:xN,x<20}
B={y:y=2n+3,nN}
n=1y=2(1)+3=5

n=2y=2(2)+3=7

n=3y=2(3)+3=9

n=4y=2(4)+3=11

n=5y=2(5)+3=13

n=6y=2(6)+3=15

n=7y=2(7)+3=17

n=8y=2(8)+3=19
For n=9, we will get y=21 but 2120 universal set has values less than 20.

B={5,7,9,11,13,15,17,19}
