Answer 6

problemsolver is right...only b

Answer 7

sequence can be like -2,0,2,3,6

Answer 8

nope ...... 6=2*3

Answer 9

-1<0<1<2<6

Answer 10

oops ... will be -3 , 0 , 1,2 ,6

Answer 11

How so?

Answer 12

well... we must prove other options are not right for example suppose a=0 then

b=1 c=2 d=3 ------> contradiction

because 0<1<2<3<6 ,,, 6=2*3

Answer 13

Ah, i see..

Answer 14

if c=0 then a must be negative and b must be positive this is contradiction again since 0>b

Answer 15

for d u can prove like prev proof for c=0
