15, 30, 45, 60 ... (15 + (n - 1)*15 ) ...

n = 5

15 + (5 - 1)*15

15 + 4 * 15

15 + 60

75

n = 6

15 + (6 - 1)*15

15 + 5*15

15 + 75

90

n = 7

15 + (7 - 1)*15

15 + 6*15

15 + 90

105

75, 90, 105

Step-by-step explanation:

add 15 but if you dont know that its fifteen you can do 30 minus 15 and it gives you 15
