Write each of the following sets in Roster form and write the cardinal number of each :
E = {x: x = 2n-1, n=N and n<6}​

1 thought on “Write each of the following sets in Roster form and write the cardinal number of each :<br />E = {x: x = 2n-1, n=N and n<6}​”

1. Step-by-step explanation:

   E = {x: x = 2n -1, n ∈ N, n < 6}

   n < 6

   1, 2, 3, 4, 5

   2n – 1

   n = 1 2(1) – 1 = 2 – 1 = 1

   n = 2 2(2) – 1 = 4 – 1 = 3

   n = 3 2(3) – 1 = 6 – 1 = 5

   n = 4 2(4) – 1 = 8 – 1 = 7

   n = 5 2(5) – 1 = 10 – 1 = 9

   therefore the set E = {1, 3, 5, 7, 9}

   cardinal number of set E = 5

   Hope you get your answer
