Find the Outlier: Analyzing the Sequence 13, 53, 33, 34, 93

To identify the odd one out from the numbers $13, 53, 33, 34, 93$, we will look at the sum of the digits:

• For $13$, the sum of the digits is $1 + 3 = 4$.
• For $53$, the sum of the digits is $5 + 3 = 8$.
• For $33$, the sum of the digits is $3 + 3 = 6$.
• For $34$, the sum of the digits is $3 + 4 = 7$.
• For $93$, the sum of the digits is $9 + 3 = 12$.

Now, observe that all the numbers except for $34$ have the digit '3' appearing in the tens place. $34$ is the only number where the digit '3' appears in the ones place instead of the tens place.

Therefore, the number that is the odd one out is $34$.
