A sequence can be generated by using an=an−1+4, where a1=5 and n is a whole number greater than 1.

What are the first 5 terms in the sequence?


5, 20, 80, 320, 1280

4, 9, 14, 19, 24

4, 20, 100, 500, 2500

5, 9, 13, 17, 21

The first 5 terms of the arithmetic sequence are: 5, 9, 13, 17, 21.

How to find the first 5 terms?

Here we have an arithmetic sequence, such that the recursive formula is:

[tex]a_n = a_{n- 1} + 4[/tex]

Such that:

a₁ = 5.

Using that formula we can get the next 4 terms. For the second term we use n = 2, so we get:

[tex]a_2 = a_1 + 4 = 5 + 4 = 9[/tex]

For the third term we have:

[tex]a_3 = a_2 + 4 = 9 + 4 = 13[/tex]

For the fourth term we have:

[tex]a_4 = a_3 + 4 = 13 + 4 = 17[/tex]

For the fifth term we have:

[tex]a_5 = a_4 + 4 = 17 + 4 = 21[/tex]

Then the first 5 terms of the sequence are:

5, 9, 13, 17, 21.
