Question: In a series of numbers, 2, 4, 8, 16, 32, 64, 128, which number is the odd one out?

Options:

Correct Answer: 2

Solution:

All numbers except 2 are powers of 2. 2 is not a power of 2 in this context.

In a series of numbers, 2, 4, 8, 16, 32, 64, 128, which number is the odd one out?

In a series of numbers, 2, 4, 8, 16, 32, 64, 128, which number is the odd one out?

Step 1: Look at the series of numbers: 2, 4, 8, 16, 32, 64, 128.
Step 2: Identify what a power of 2 is. A power of 2 means a number that can be expressed as 2 raised to an exponent (like 2^1, 2^2, 2^3, etc.).
Step 3: Check each number in the series to see if it is a power of 2.
Step 4: 2 is 2^1, which is a power of 2.
Step 5: 4 is 2^2, which is a power of 2.
Step 6: 8 is 2^3, which is a power of 2.
Step 7: 16 is 2^4, which is a power of 2.
Step 8: 32 is 2^5, which is a power of 2.
Step 9: 64 is 2^6, which is a power of 2.
Step 10: 128 is 2^7, which is a power of 2.
Step 11: Since all numbers except 2 are powers of 2, we conclude that 2 is the odd one out.

Powers of 2 – Understanding that numbers can be expressed as powers of 2, where each number in the series (except 2) is a result of raising 2 to an integer exponent.
