Question

Consider the set B={x=2n-1:n<5} write down the elements of set B, if the universal is the set of whole numbers.​

Answer 1

Answer: Set B={1,3,5,7}

Step-by-step explanation:

here, x=2n-1

      n<5 ,  the value of(n=1,2,3,4)

x = (2*1)-1=  (2-1) = 1 ---[1]

x = (2*2)-1= (4-1) = 3 ---[2]

x =(2*3)-1= (6-1) = 5 ---[3]

x = (2*4)-1= (8-1) = 7 ---[4]

therefore, Set B={1,3,5,7}
