Answer 1

a+1+a+3+a+5+a+7+a+9+a+11= 96
6a=96-36
6a=60
a=10
a1=11
a2=13
a3=15
a4=17
a5=19
a6=21

Answer 2

a |-----|
b |-----|+2|
c |-----|+2|+2|
d |-----|+2|+2|+2|
e |-----|+2|+2|+2|+2|
f  |-----|+2|+2|+2|+2|+2|           } 96.

96 - 30 = 66   ( 6 segmente egale )
66 : 6 = 11 (a)
11 +2 = 13 (b)
11 +2+2 = 15 (c)
11 +2+2+2 = 17 (d)
11 +2+2+2+2 = 19 (e)
11 +2+2+2+2+2 = 21 (f)
Verificare : 11 +13 +15 +17 +19 +21 = 96.
