Answer:

The rule is 3(5)^(n-1) where n is the term number.

Step-by-step explanation:

The constant multiplier = 15/3 = 5.

Checking that this is correct 75/15 = 5,  375 / 75 = 5.

So for term number 1 , the value is 3 , the expanded form is 3 * (5)^(1-1) and the simplified form  is 3*5^0 = 3.

Term number 2, the value is 15 , the expanded form is 3 * 5^(2-1) and the simplified form is 3 * 5^1 =15.

The other rows are calculated in the same way.

This is a Geometric sequence with common ratio 5.

The rule for the sequence is 3(5)^(n-1).
