I can't believe the variety of answers to this question. Including 81, which I've yet to see someone actually offer the math for.

People say that it depends on what "valid" variable you us, or that you have to assume this or that in the "missing" pattern, but you really don't.

The simple formula for this is x^2+x=y or if you want, x*x+x=y.

You don't even have to calculate the "missing" numbers.

9*9+9 = 81+9 = 90. So y=90.

The answer is:90

I got 56!

6 x 1 = 6 +6 = 12 (the next answer)

12 x 1 = 12 + 8 = 20 (the next answer)

20 x 1 = 20 + 10 = 30 (the next answer)

30 x 1 = 30 + 12 = 42 (the next answer)

42 x 1 = 42 + 14 = 56!!!!

If the multiplier is the unknown variable the pattern revealed below is possible by adding 1 to the multiplier. 9 would be 90

2x3 = 6

3x4= 12

4x5 = 20

5x6 = 30

6x7 = 42

7x8 = 56

8x9 = 72

9x10 = 90

60

pattern is 2x current number added to the previous answer

so

last number is 6 = 42 so

9 = (9x2) or 18 + 42

9 = 60

if 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?

 

6+3*2=12

12+4*2=20

20+5*2=30

30+6*2=42  then 

42+9*2=60

If 2 = 6,  ( 2 x 3 added to 6 = 12) hence  3 = 12: And 2 x 4 added to 12 = 20, hence 4 = 20,  And 2 x 5 added to 40 = 42, then 2 x 9 added to 42 = 60,

 

Therefore 9 = 60

if 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?

2=6(4)

3=12(6)

4=20(8)

5=30(10)

6=42(12)

7=56(14)

8=72(16)

9=90(18)

10=110(20)

 

 

9=90

it can be solved with 2 methods. 1st method. 2x3=6 3x4=12 4x5=20 5x6=30 6x7=42 then 9x10=90 2nd method 2x2=4. 4+2=6 3x3=9. 9+3=12 4x4=16. 16+4=20 5x5=25. 25+5=30 6x6=36. 36+6=42 then 9x9=81. 81+9=90. So 90 is the Correct Answer.

6/2 =3

12/3 =4

20/4 =5

30/5 =6

42/6 =7

The answer keeps increasing by1.

So 

x/9 =8

x =9*8

x =72

answered Nov 11, 2013 by anonymous

Para ser 90, a matriz precisava deixar claro que existe o 7 e 8.

Isto não ocorre. Acredito que o resultado mais provável seja 58, pois o resultado é sempre a soma dos números da esquerda , diagonal acima e superior + 1:

12 =( 6 + 3 + 2) + 1

20 =(12 + 4 + 3) + 1

30 = (20 + 5 + 4) + 1

42 = (30 + 6 + 5) + 1

?? = (42 + 6 + 9) + 1 = 58

if 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?

I think is: Number X Next position Number from the given variables.

2 = 6 , so 2x3=6

3 = 12, 3x4=12

4 = 20, 4x5 = 20

5 = 30, 5x6 = 30

6 = 42, 6x7 = 42

9  = 9x10 = 90

This is easy..The answer is simply... 9

once you guys realize that this isn't really a math problem & that the whole equation is incorrect..Then you'll understand why...the answer is..... 9
answered Mar 28, 2014 by Big Fred
2 = 6

3 = 12 (+ 6)

4 = 20 (+ 8)

5 = 30 (+ 10)

6 = 42 (+12)

7 = 66 (+14)

8 = 82 (+ 16)

9 = 100 (+ 18)

Each successive number is arrived at by adding a progressively larger number (larger by 2) to the result.

9. Or, if you're willing to accept the abuse of the equality sign in the proposition, continue the pattern "x=x*(x+1)" to get 90.
answered May 23, 2014 by anonymous

7 and 8 are not there ... use the numbers shown ..... add 2 numbers plus the previous total to get the next total 3+3+6=12 / 4+4+12=20 / 5+5+20=30 / 6+6+30=42 / 9+9+42=60

the answer is simple, the answer is there is no answer, because 2 does not equal 6 and 3 does not equal 12 and so on, true there is a patern but that's just there to trick you, but what if there wasn't a patern? most people would have got the answer because they gave up on what they learned at school or what they were taught

Este problema no tiene solucion, o bien, no tiene una solucion unica.

Si se pretende seguir un razonamiento matematico a este problema, ya de partida las condiciones iniciales no lo son, por ejemplo, 2 no es igual a 6.
