Question

1,2,3,4=10,,2,5,4,7=30,, 4,6,1,3=?

Answer 1

The answer to 4, 6, 1, 3 = 20.

Step-by-step explanation:

We are given the following patterns below;

1, 2, 3, 4 = 10

2, 5, 4, 7 = 30

4, 6, 1, 3 = ?

First we have to find a particular pattern, then we will solve for the last series.

Considering first the series: 1, 2, 3, 4 = 10

Here the first term = 1, second term = 2, third term = 2, and fourth term = 4

Subtracting second and first term we get ;

2 - 1 = 1

Similarly, subtracting fourth and third term we get ;

4 - 3 = 1

Now, subtracting both the differences = 1 - 1 = 0

This means that in number 10, the 1 is achieved by subtracting the terms and 0 is achieved by subtracting both the differences.

Considering the second series: 2, 5, 4, 7 = 30

Here the first term = 2, second term = 5, third term = 4, and fourth term = 7

Subtracting second and first term we get ;

5 - 2 = 3

Similarly, subtracting fourth and third term we get ;

7 - 4 = 3

Now, subtracting both the differences = 3 - 3 = 0

This means that in number 30, the 3 is achieved by subtracting the terms and 0 is achieved by subtracting both the differences.

Similarly, in the series 4, 6, 1, 3 = ?

Here the first term = 4, second term = 6, third term = 1, and fourth term = 3

Subtracting second and first term we get ;

6 - 4 = 2

Similarly, subtracting fourth and third term we get ;

3 - 1 = 2

Now, subtracting both the differences = 2 - 2 = 0

This means 4, 6, 1, 3 = 20.
