• A. rule
• B. method
• C. algorithm
• D. pattern

Answer 1

The correct option is D pattern

A repeated arrangement of numbers or shapes which follows a rule is called a pattern.
For example, $1,3,5,6,7,...$
Here, after $1$, the next number is $3$, i.e., we are adding 2 with $1$.
After $3$, the next number is $5$, i.e., we are adding $2$ with $3$.
So, the change is going in the same way, that is, we are adding 2 to the current number.
So, there is a repeated arrangement of numbers that follows a rule of adding $2$ to every number to get the next number. For example, after $1$, it would be $3$; after $3$, it would be $5$ ; after $5$, it would be $7$, and so on.
This is called a pattern.
