Answer 2

___

abc → numar natural, cu a ≠ 0; a + c = 4; b = 0;  1; 2; 3; 4; 5p; 6; 7; 8; 9

a + c = 4

a = 1, c = 3  ⇔ abc = 103; 113;  123;  133; 143; 153; 163; 173; 183; 193

a = 2 ⇒ c = 2⇔ abc = 202;  212;  222;  232;   242;  252;  262;  272;  282; 292

a = 3 ⇒ c = 1 ⇔ abc = 301; 311;  321;  331;  341;  351;  361; 371;  381;  391;

a = 4 ⇒ c = 0⇔ abc = 400;  410;   420;   430;   440;   450;  460;   470;   480;  490
