Question

E = {x : x = 2n-1, n∈N and n < 6).
Write in Roster Form.​

Answer 1

For n belongs to N and n < 6, the only values n can take are : 1, 2, 3, 4, 5.

Hence put the values of n in X = 2n-1

So from n = 1 to n = 5, we get X = 1, 3, 5, 7, 9

Therefore, The roster set for these values are

E = {1, 3, 5, 7, 9}

Hope you find this useful :)
