It is an arithmetic progression. Note the general rule for AP sequences:
a(n) = a(1) + (n - 1)d
a(1) = 12a (first term)
d = 3a (common difference)
General rule: a(n) = 12a + (n - 1)*3a
First we must find the percentage of our number
Because our number is 72 we have to find 25% of it
Simple way
<em>25% of 72 is another way of saying 25% times 72</em>
<em />
25% x 72
= 18
Answer

<em>P.S: if you want you can multiply in fraction form and still get the same answer</em>
