What is a missing number in a sequence?

Back

A missing number in a sequence is a number that follows a specific pattern or rule that is not explicitly stated. To find it, you need to identify the pattern in the given numbers.

Front

How do you identify a pattern in a number sequence?

Back

To identify a pattern, look for consistent differences or ratios between numbers. For example, if each number increases by 2, the pattern is an addition of 2.

Front

What is the rule for the sequence: 10, 12, 14, ?

Back

The rule is to add 2 to the previous number. The missing number is 16.

Front

What is the rule for the sequence: 20, 18, 16, ?

Back

The rule is to subtract 2 from the previous number. The missing number is 14.

Front

What is a two-step pattern?

Back

A two-step pattern involves two operations to find the next number, such as adding 3 and then multiplying by 2.

Front

How do you solve for a missing number in a two-step pattern?

Back

First, apply the first operation to the last known number, then apply the second operation to the result to find the missing number.

Front

What is the missing number in the sequence: 5, 10, 15, ?

Back

The rule is to add 5. The missing number is 20.

Front

What is the missing number in the sequence: 100, 90, 80, ?

Back

The rule is to subtract 10. The missing number is 70.

Front

What is a number table?

Back

A number table is a visual representation of numbers arranged in rows and columns, often used to identify patterns or rules.

How do you find a missing number in a number table?

Back

Look for patterns in the rows or columns, such as consistent addition or subtraction, to determine the missing number.
