Answer 1

Given :   {3,7/3,13/7}

To Find : Write in set builder form

Solution:

A = {3,7/3,13/7}

3 = 3/1   = (2² - 1) /(1² - 0)

7/3  =   ( 3² - 2) / ( 2² - 1)

13/7    = ( 4²  - 3) / ( 3² - 2)

((n + 1)² - n ) / (n² - (n - 1))    =  (n² + n + 1) / (n² - n + 1)

A = {  (n² + n + 1) / (n² - n + 1)  : n ∈ N , n ≤ 3 }

set builder form =  { (n² + n + 1) / (n² - n + 1)  : n ∈ N , n ≤ 3 }
