ok i understand i did a way which i wasn't supposed to but my head is really foggy atm and i jus need to tell you the answer asap cus you're prob in a online quiz or such.
all i did was multiply starting from 1 to 5. Then i realized that multiplying each number by 3 will give you a total of 27 subs. Ik its not convient but im certain its the right answer. Good luck
