Can you add a picture? I don't see a circle. I will answer this question if you add a picture.
The answer is 168 logs.
1st row: 15 logs
2nd row: 18 logs
3rd row: 21 logs
(so, each row has 3 more logs)
4th row: 24 logs
5th row: 27 logs
6th row: 30 logs
7th row: 33 logs
The sum of logs from each row is: 15 + 18 + 21 + 24 + 27 + 30 + 33 = 168 logs
It seems to be none of the above
Answer:
sum of a number 2 plus3 is equal to 5
and less than its double 2×2=4 so the answer is 2
