The given sequence is an ''Arithmetic sequence'' with common difference 5.

What is Arithmetic sequence?

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

We have to given that;

The sequence is,

⇒ 2, 7, 12, ...

Now, We can find the common difference as;

The sequence is,

⇒ 2, 7, 12, ...

Common difference = 7 - 2 = 5

Common difference = 12 - 7 = 5

Hence, It is an Arithmetic sequence.

Thus, The given sequence is an Arithmetic sequence with common difference 5.
