Question

Write an arithmetic sequence with common difference 3

a) Will the difference between any two terms in this sequence be 40? Why?

b) Is 280 a term of this sequence?

c) Write the algebraic form of that sequence?

​

Answer 1

Step-by-step explanation:

In an Arithmetic Sequence the difference between one term and the next is a constant.

3

In other words, we just add the same value each time ... infinitely.

Example:

1, 4, 7, 10, 13, 16, 19, 22, 25, ...

This sequence has a difference of 3 between each number.

The pattern is continued by adding 3 to the last number each time, like this:

arithmetic sequence 1,4,7,10
