Question

The first three terms of an arithmetic sequence are as follows.

Answer 1

16 and 20

Explanation:

In the arithmetic squence, we can tell that 4 is being added to each term.

Thus, we obtain the following rule:

• 4x [Where "x" is the xth term]

To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.

Determining the 4th term of the sequence:

⇒ 4x

⇒ 4(4)

⇒ 16

Determining the 5th term of the sequence:

⇒ 4x

⇒ 4(5)

⇒ 20

Thus, the next two terms are 16 and 20.

Answer 2

16,20

Explanation:

As shown, you add four by each.

4+4=8

8+4=12

So, 12+4=16

16+4=20
