Answer 1

b = a+2
c=a+4
d=a+6
e=a+8
f=a+10
g=a+12
a+a+2+a+4+a+6+a+8+a+10+a+12=350
7a+42=350
7a=350-42
7a=308
a=308÷7
a=44
b=44+2=46
c=46+2c=48
d=48 +2=50
e=50+2=52
f=52+2=54
g=54+2=56

Answer 2

a+a+2+a+4+a+6+a+8+a+10+a+12 = 350
7a + 42 = 350

7a =308
a =44

a+2= 46
a+4= 48
a+6 =50
a+8 =52.
a+10=54
a+12=56

Nr sunt: 44 , 46 , 48 , 50 , 52 , 54 , 56
