I am not understanding this

Answer 2

4 53 1

Given: 3 42 1

5 82 3

6 84 2

4 ? 1

To Find: The missing number

Solution: Let, the missing number be x.

In the first series 3 42 1

We can see that the first digit of the middle number i.e., 4 is the sum of the first and last number.

3 + 1 = 4

Now, if we see the second digit of the middle number i.e., 2. It is the difference between the first and last numbers.

3 - 1 = 2

Similarly, in the second series 5 82 3

First number + last number = First digit of the middle number

5 + 3 = 8

The first number - last number = Second digit of the middle number

5 - 3 = 2

A similar pattern can be seen in the third series also.

Now, we can find the middle number of the fourth series.

First number + last number = First digit of the middle number

4 + 1 = 5

The first number - last number = Second digit of the middle number

4 - 1 = 3

Therefore, the first digit and second digit of x are 5 and 3.

Hence, the required number is 53.
