Răspuns :

a ) 13 + 15 = 28

28 : 2 = 14 ( media artimetica )

b ) 4 + 8 = 12

12 : 2 = 6 ( media artimetica )

c ) 2 + 20 = 22

22 : 2 = 11 ( media artimetica )

d ) 143 + 1 = 144

144 : 2 = 72 ( media artimetica )

e ) 57 + 49 = 106

106 : 2 = 53 ( media artimetica )

f ) 99 + 37 = 136

136 : 2 = 68 ( media artimetica )
