Answer 3

1 + 4 = 5

5 + 2 + 5 = 12

12 + 3 + 6 = 21

21 + 8 + 11 = 40

Answer 4

1 + (1 x 4) = 5

2 + (2 x 5) = 12

3 + (3 x 6) = 21

8 + (8 x 11) = 96 or

Answer 5

either 40 or 96

Answer 6

this is the second what have wrote me on facebook.com but this 40 is true too than i will rewrite these equations in this line

1 + 4 = 5

3 + 6 = 18

8 + 11 = ?

5 + 2 = 12

so in this case what will be the right answer ?

Answer 7

sorry there is 2 + 5 = 12 the last one line

Answer 8

so in this order wrote these equations can being 40 true again too ? i think not

Answer 9

in this case just 96 is the right answer

Answer 10

No Its not 40

Answer 11

I think only 96 is the correct answer

Answer 12

Loser
