bonsoir,
-Suite logique: -120; -60; -20; -5
→Explications:
-120 * 1\2 = -60
-60 * 1\3 = -20
-20 * 1\4 = -5
.

.
x . 1\n+1 = y
-Suite logique: 28; 20; 10;-2
→Explications :
28 -8 =20
20 -10 =10
10 -12 =-2
-2 -14 =-16
etc
-Suite logique: -50; -26; -14;-8;-5
→Explications :
-50 + 24 = -26
-26 + 12 = -14
-14 + 6 = -8
-8 + 3 = -5
