Generate Number Sequences

In this activity, we will be given a sequence rule and we will generate that sequence!

Let's look at a sequence:

3, 7, 11, 15, 19, ....

We can see that the rule of the sequence is add 3 

We are going to do this in reverse.

That is, we will be given the first term and a rule and will find the next four terms of the sequence. 

Let's look at a typical question!

Example

The first term of a sequence is 4 and follows the rule add 5

What is the 5th term of this sequence?

Answer

The 1st term is 4

The 2nd term is 4 + 5 = 9

The 3rd term is 9 + 4 = 13

The 4th term is 13 + 4 = 17

The 5th term is 17 + 4 = 21

Answer = 21

Let's try some of these!
