Identify the sequence as arithmetic, geometric, or neither 3, 4.5,6,7.5

In an arithmetic sequence we have a common difference (d).

Common difference: The common difference is the difference between two numbers in an arithmetic sequence.

So let us find common difference for the given sequence:

3, 4.5,6,7.5

Here first term is 3,

second term is 4.5

Difference = second term - first term = 4.5 - 3 = 1.5

third term is 6,

Difference = third term - second term = 6- 4.5 = 1.5

So common difference is 1.5

So we can say that the given sequence is an arithmetic sequence.
