Answer 2

5) 22, 30, 24, 40, 26, 50, 28, 60, 30, 70

33, 15, 33, 17, 33, 19, 33, 21, 33, 23

6) 51, 53, 55, 57, 59

7) Z+U=9 => (Z,U) = (1,8), (2,7), (3,6), (4,5), (5,4), (6,3), (7,2), (8,1), (9,0)

Z<U => (Z,U) = (1,8), (2,7), (3,6), (4,5).

Numerele: 18, 27, 36, 45

Z-U=3 => (Z,U) = (9,6), (8,5), (7,4), (6,3), (5,2), (4,1), (3,0)

Z<7 => (Z,U) = (6,3), (5,2), (4,1), (3,0)

Numerele: 63, 52, 41, 30

Z+U=7 => (Z,U) = (1,6), (2,5), (3,4), (4,3), (5,2), (6,1), (7,0)

Z>U => (Z,U) = (4,3), (5,2), (6,1), (7,0)

Numerele: 43, 52, 61, 70

8) Întotdeauna, diferența dintre două numere pare sau impare consecutive este 2.

9) Cel mai mic număr impar cu suma cifrelor 9 este 27.
