Răspuns:

a. x ∈ ℕ , x < 14 , x- nr par => x={0,2,4,6,8,10,12}

b. x ∈ ℕ , x < 11 , x- nr impar => x={1,3,5,7,9}

c. x ∈ ℕ , x divizibil cu 5 , x - nr par => x={10,20,30,40,50,60,70,80,90}

d. x ∈ ℕ , x divizibil cu 25, x < 123  => x={25,50,75,100}

e. x ∈ ℕ , x- nr de 3 cifre => x={111,222,333,444,555,666,777,888,999}
