Question

# Choose the rule to describe this pattern.

56, 53, 50,47

- Subtract 2
- Subtract 3
- Subtract 4
- Add 3

Hint:

### In mathematics, a number pattern is a series of integers that occur in a specific order. Patterns often describe the inverse relationship between numbers. Patterns can also be used to describe numerical sequences. Here we have given a series of numbers that is 56, 53, 50,47 We have to find the rule that is used in this pattern.

So here first we will try to find the common difference which will result in the rule.

## The correct answer is: Subtract 3

### So as we know that a pattern or sequence in a series of numbers is called a number pattern. Generally, this pattern builds a connection between all integers.

Some numerological pattern types are:

There are two typical patterns for number sequences:

- Arithmetic Sequences
- Geometric Sequences

The following are some examples of Number Patterns' unique sequences:

- Square Numbers
- Cubic Sequence
- Triangular Numbers
- Fibonacci Numbers

A common difference is a difference between two consecutive terms of an arithmetic progression. The formula to find the common difference in an arithmetic sequence is:

- d = a(n) - a(n - 1)

where a(n) is n term in the sequence, and a(n - 1) is the previous term (or (n - 1) term) in the sequence.

We have been given the series 56, 53, 50, 47

d = 47 - 50 = -3

d = 50-53 = -3

So the common difference is -3. The rule is to subtract 3 from the previous term.

Here we were given a number pattern and we have to find the rule used in that. There are numerous different sorts of number patterns. They could be a series of even or odd numbers, multiples of a specific number, ascending or descending, etc. So the common difference is -3. The rule is to subtract 3 from the previous term.
