Median of 18, 35, 10, 42, 21 will be

Question

Accepted Answer

To determine the median of the given set of numbers, we first need to arrange the numbers in ascending order. The numbers provided are 18, 35, 10, 42, and 21. Arranging these numbers in ascending order gives us: 10, 18, 21, 35, 42.

The median is the middle number in a set of numbers arranged in order. Since there are five numbers in this set, the median will be the third number in the ordered list. In this case, the third number is 21.

Therefore, Option 3, which is 21, is the correct answer.

Now, let's explain why the other options are incorrect:

1. **Option 1 (18):** This number is the second number in the ordered list, not the middle number. Therefore, it cannot be the median.

2. **Option 2 (10):** This number is the first number in the ordered list. Since the median is the middle number, 10 cannot be the median.

3. **Option 4 (5):** This number is not even part of the original set of numbers. Therefore, it cannot be the median.

In conclusion, the correct answer is Option 3 (21) because it is the middle number in the ordered list of the given set of numbers.
