each number is larger by 4 from the previous18+14=32+18=50+22=72+26=98+30=128+34=162+38+=200
3=18

• pokey

I agree 200
this is how I did it too

• Tom

That is exactly how I did it too.

• Ernest Arthur

Square the number x and multiply the answer by 2. 10 square is 100×2=200

• nayyef

200=10*10 *2 =200

• Ian Jones

10 _ 200 agree with the folks who say this for the same reason

• Jill

Mt answer 1s 10 x 16 = 160

• Robert

200.

3x (3×2) = 6
4 x (4×2) = 32
5x (5×2) = 50

etc.. so 10 x (10×2) = 200

200

This is one of those puzzles where the way you view it determines whether you can get to a correct answer or not. View it the wrong way and you might never get there.

This is a simpler problem so I’m surprised by the 99.9% have failed to work it out statistic. But then, that also happens in my profession which is designing other people’s products for them. In our case, electronics based products that are intended to be manufactured in Australia. Some of our work is designing a product that other people have previously had a go at but didn’t succeed.

It will be interesting to see what the statistics are for the people who contribute to this blog. I’m betting they are better than average.

the answer is 160. there is a pattern where each Number on the right is multipled with an even number incrementaly from 6, , 10, 12, 14 then 16 for 10.

• Juno

Nope, its 200. Geometric progression

• moutaz abd el salam al sharqawi

8*16=128
9*18=162
10*20=200

• Martin

I’m getting 200.

• Geraldine Gilchrist

The answer to this math problem is
10= 116.

• Geraldine Gilchrist

You would add 18 to 98. So that make 10= 116

• Andrew

• Marius

The number on the right side is the number on the left side square then times two.
10 = 10 × 10 × 2 = 200
If you try to solve a pattern, note the left column skips from 7 to 10,therefore the right column must also skip two rows.

(Number squared) x 2
10 squared x 2 =200
(10 x 10) x 2 = 200

9 = 162
(9 x 9 ) x 2 = 162
81 X 2 = 162

8 =128
8 squared x 2 = 128
(64 x 2 = 128

you can get to 10 because the given facts do not have a 1 or 0 to consider

3×6=18,4×8=32,5×10=50,etc… 10×20=200

• sandra

Looks like math is better than typing. My previous reply should have been “you cannot get to …”

• saffar

4*8=32
5*10=50
6*12=72
7*14=98
10*20=200

• Judith

160 is the answer The multiplier each time is 2 more

3x 6 = 18
4x 8 = 32
and so on until
10x 16 = 160

• howard

10 = 160. The pattern is 3×6 =18, 4×8=32, 5×10= 50 etc etc…

• Jan Arne Nilsen

3 x 6 = 8
4 x 8 = 32
5 x 10 = 50
6 x 12 = 72
7 x 14 = 98
8 x 16 = 128
9 x 18 = 162
10 x 20 = 200

• Jolie Owmby

3×6=18; 4×8=32; 5×10=50; 6×12=72; 7×14=98; 8×16=128; 9×18=162; 10×20=200
A × B = C; B in each next equation is always 2 more than before.

• Jolie Owmby

A × B = C; B in each next equation is always 2 more than before, so 10 = 200

• Jamie

200
The difference each time is increasing by 4, so for ten it would be 162 + 38

• Mark

200, because the difference between each pair of numbers on the right increases by four each time.

• Francis TD

last# divided by first! Double the result to #10 which is 20 hence answer= 200

• Ian

Because 10^2 = 100
100 x 2 = 200

• Barry

3*6=18
4*8=32
5*10=50
6*12=72
7*14=98

10*20=200

• Andrew

Numbers progress as follows:

8×16
9×18
10×20=200

• Farah

• Gavin Robertson

3 x 6 = 18
4 x 8 = 32
5 x 10 = 50
6 x 12 = 72
7 x 14 = 98
8 x 16 = 128
9 x 18 = 162
10x 20 = 200

• Ali

3*6=18
4*8=32
5*10=50
6*12=72
7*14=98
Numbers go on an even numbers like this; 6,8,10,12,14 etc.

• ynga

7=98
8=98+30
9=128+34=162
10=162+38= 200

• annie

I got 200 as an answer but took a really long way to get there; I started with 3=18 and then substracted the 3 and got 15 or 3×5; 4 = 32 became 32-4 or 4 x 7; following on 7 = 98 became 98 – 7 or 7×13 which then led me to 10 x19 which is 190 plus the original 10 which is 200. I think it was a complete fluke that I got the same answer as most of you.
