Answer :
To determine which number is odd in the given series, you need to check each number to see if it is even or odd. An odd number is any integer that is not evenly divisible by 2.
Let's examine each number in the series:
110: This number is even because it ends with a 0, which is divisible by 2.
156: This number is even because it ends with a 6, which is divisible by 2.
210: This number is even because it ends with a 0, which is divisible by 2.
272: This number is even because it ends with a 2, which is divisible by 2.
342: This number is even because it ends with a 2, which is divisible by 2.
424: This number is even because it ends with a 4, which is divisible by 2.
After checking all the numbers, none appear to be odd, so let's re-evaluate the problem with the given options:
Options: 156, 272, 424, 342
As reviewed, all numbers in the series, as well as the options provided, are even. It appears there might be an oversight in identifying an odd number; however, if there was any typographic change resulting in an odd number option, the steps shown would help recognize it.
In short, all provided numbers are even, and none is odd based on the series currently analyzed.
