i saw a pattern. 4,6,8,10,12,14

2 + 4 = 6

6 + 6 = 12

12 + 8 = 20

20 + 10 = 30

30 + 12 = 42

42 + 16 = 56

I saw the same pattern, but just in the answer. Where the difference in the answer starts with a factor of 6, and then each “answer” is increased by 2. Which makes 9=84. I’m glad I’m not the only one who saw it that way.

I get 72. The numbers shown indicate the multipliers from top to bottom (where = sign is) are 3, 4, 5, 6, 7. The next number would be an 8. 9×8=72.

You can also say, doubling the number below and adding it to the answer above gives you the next answer…(3×2)+6= 12

(4×2)+12=20

(5×2)+20=30

(6×2)+30=42

(9×2)+42=60

Result 60

right 6

6 + 6 = 12

12 + 8 = 20

20 + 10 = 30

30 + 12 = 42

= X

left 2 (+1)

3 (+1)

4 (+1)

5 (+1)

6 (+1)

9 (+3)

>> left to right

2 = 6

+ (2×3)

3 = 12 X

+(2×4)

4 = 20

+(2×5)

5 = 30

+ (2×6)

6 = 42

+ (2×9)

9 = 60

2=6. .+.6 =12

3=12. +.8 =20

4=20. +10 =30

5=30. +12 =42

6=42 .+14 =56

7=56. +16 =82

8=82. +18 =100

9=100 .+20 =120

___________________

second line even numbers to the answes…

I saw a different pattern 5=30 6=42 7=56 8=72 9=90. Each answer goes higher by 2. 30-42 is 12,42-56 is 14, 56-72 is 16,72-90 is 18

2=6 –> difference is 4 –> 2*2

3=12 –> difference is 9 –> 3*3

4=20 –> difference is 16 –> 4*4

5=30 –> difference is 25 –> 5*5

6=42 –> difference is 36 –> 6*6

9=58 –> difference is 49 –> 7*7

Ya…Sella Great Work This Is A Another Pattern I Never Thought So..!! Grr8 Thank You..!!

My answer is 58.

2+4=6

3+9=12

4+16=20

5+25=30

6+36=42

9+49=58

Because:

4+5=9

9+7=16

16+9=25

25+11=36

36+13=49

(Follow the odd number.)

Ohh…!!! I SEE Now Another Pattern ….Great !!! Gad !! I M Glad It’s Math…So Many Solutions And Answers…!! 🙂

If you see Left hand Side Numbers..Its Just One Of Patterns! 2*3= 6 Matches the RHS first No. 6

3*4= 12 Matches the RHS Second No. 12

4*5= 20 ” ” third No. 20

5*6= 30 ” ” Fourth No. 30

6*7= 42 ” ” Fifth No. 42

7 & 8 Are Missing So We Have to Go According to Pattern

So, 7*8= 56 ” ” Sixth No. Will Be 56

8*9= 72 ” ” Seventh No. will be 72

9=??? So, 9*10=90 ” ” Eight No. Will Be 90

So Ans Is 90.

I Hope You Understand!! Thanks for Your Valuable Comments!! Thank You.

I don’t want to change the question.Such as adding in 7 or 8.The question is 2,3,4,5,6,9.

I also have the same answer-90.But in another ways.

2*2+2=6

3*3+3=12

4*4+4=20

5*5+5=30

6*6+6=42

9*9+9=90

(Don’t change the question by adding other numbers.)

Another solution is use the formula n+(n)to power 2 : where n is any number on left column .hence try n= 2 so 2 + (2) to power 2 = 6 , n=3 so 3+(3) to power 2= 12 , until n=9 so 9+(9)to power 2=90 anwer. therefore any positive number on left column, example if beginning number is 20 so 20 +(20)to power 2 =420. but negative number is not applicable to this formula.

If you multiple it: 2=6 2×3=6 3=12 3×4=12 4=20 4×5=20 5=30 5×6=30 6=42 6×7=42 7=56 7×8=56 8=72 8×9=72 9=?? 9×10=90So your answer is 9=90. I got the answer by one number higher then the number before the equal sign. so 2×3, 3×4, 4×5 and so on. My work on the right show you how I got my answer.

Or you can have the same result with an other way. The probleme come with a false equation 2=6 so it’s like you said 2 banana equal 6 apple, so 3 banana = 12 pears, ect you can deduct the paterns like this

2=6

3=12 (so last result +6)

4=20 (so last result +8)

5=30 (so last result +10)

6=42 (so last result +12)

7=56 (last result +14)

8=72 (last result +16)

9=90 (last result +18)

6,8,10,12,14,16,18

Just add + 2
