In the series 10, 20, 30, 40, 50, 60, 70, 80, 90, which number is the odd one out?

In the series 10, 20, 30, 40, 50, 60, 70, 80, 90, which number is the odd one out?

Step 1: Look at the series of numbers: 10, 20, 30, 40, 50, 60, 70, 80, 90.
Step 2: Identify what all the numbers have in common. They are all multiples of 10.
Step 3: Check each number to see if it fits the pattern of being a multiple of 10.
Step 4: Notice that 90 is the last number in the series.
Step 5: Realize that while 90 is a multiple of 10, it is not part of the sequence of 10s that are increasing by 10 each time.
Step 6: Conclude that 90 is the odd one out because it does not fit the pattern of the increasing sequence.
