Question

What is the common difference d of the sequence? −15, −4, 7, 18, 29, ...

Answer 1

Answer:

The common difference is $11$

Step-by-step explanation:

we know that

In an Arithmetic Sequence the difference between consecutive terms is a constant called the common difference

so

In this problem we have

$-15,-4,7,18,29,...$

Let

$a1=-15\ a2=-4\ a3=7\ a4=18\ a5=29$

Find the difference between consecutive terms

$a5-a4=29-18=11$

$a4-a3=18-7=11$

$a3-a2=7-(-4)=11$

$a2-a1=-4-(-15)=11$

therefore

The sequence is an Arithmetic Sequence

The common difference is $11$

Answer 2

I think that it is 11...
