# What is the next number 3, 6, 4, 8, 6, 12, 10, ...?

Series is solved using the relation between the consecutive terms.

## Answer: The final term of the series will be 20.

Go through the steps to understand the solution.

**Explanation:**

Given series: 3, 6, 4, 8, 6, 12, 10, ...

Relation between 1^{st} number and 2^{nd} number = 1^{st} number × 2 = 2^{nd} number

Difference between 3^{rd} number and 2^{nd} number = 4 - 6 = -2

Relation between 3^{rd} number and 4^{th} number = 3^{rd } number × 2 = 4^{th} number

Difference between 5^{th} number and 4^{th} number = 6 - 8 = -2

Relation between 5^{th} number and 6^{th} number = 5^{th }number × 2 = 6^{th }number

Difference between 7^{th }number and 6^{th} number = 10 - 12 = -2

Relation between 7^{th} number and 8^{th} number = 7^{th} number × 2 = 8^{th} number

⇒ 8^{th} number = 7^{th} number × 2 = 10 × 2 = 20

So, 8^{th} term is 20
