I'm so sorry if its not but I would guess it is :)
It would be: 567/18 = 31.5
So, she needs atleast 32 shelves....
Answer:
372
There are already 3 terms. So, now you have to find the 30th term.
The difference of 30 - 3 is 27. Now, since you add 9 for every term, multiply it by 27.
27 x 9 = 243.
The third term is 29. So you add 29.
Your answer will be 372. Hope it helps.
