Answer:
3 5 7 9
Explanation:
First, integer 1 is stored in variable num.
In the while statement, the condition is 1*1 <=50 (Which is true)
If that condition is met, we add 2 to variable num, resulting in 3.
The condition fails at 8 because 8*8 is 64, but the condition is met at 7*7 which is 49 and then we add 2 in variable num, resulting in 9.
