Which One Doesn’t Belong? Why?

[Judy Winslow]

These have more than one answer.

 

[Judy Winslow]

9 because if you add the digits of the others they all equal 7.

 

[Rubato]

43 cause it’s supposed to be 36

 

[Judy Winslow]

43 cause it’s supposed to be 36

Why is it supposed to be 36

 

[konceptjones]

43, because 9+16=25

also

9 because increase the 10's by 1 and reduce the 1's by 1: start with 16 and you get 25
25 becomes 34
34 becomes 43

 

[Judy Winslow]

16 because it’s the only even number.

 

[konceptjones]

16 because it’s the only even number.

literally just realized this.

 

[Judy Winslow]

43 because it’s the only number with the larger digit in the tens place.

 

[Judy Winslow]

Nope. That’s wrong.

 

[Valentinez A. Kaiser]

43 because all the other numbers are squared

9 = 3 x 3
16 = 4 x 4
25 = 5 x 5

 

[Inori]

yeah I overthought this one

43 cause it’s supposed to be 36

I was gonna say its supposed to be 34 instead

 

[xMaineEventx]

9 because it's not in sequence. Everything else goes 123456...

 

[The Lonious Monk]

My first thought was 43 because it's the only number that's not the square of another number. Somebody already said that though, so I'll say 43 because it's the only prime number.

This is one of those questions that is supposed to invoke conversation and thinking because there’s no wrong answer

I like these

 

[mryounggun]

16. It's the only even number.

 

[BRIAN B.]

all of em


then all the boxes are the same... green

 

[Rubato]

Well actually the literal question asked was which 1 doesn’t belong, not which number doesn’t belong, and the only 1 is the 1 in 16

 

[ImaInfluenza]

I thought 16 because the others are all prime numbers

 

[Rubato]

I thought 16 because the others are all prime numbers

Explain what you think a prime number is

 

[konceptjones]

I thought 16 because the others are all prime numbers

yeah, 16 ain't a prime number by any stretch of the imagination, New Math, or Common Core.

43 is the prime number of the bunch as @The Lonious Monk already pointed out.
