To go to sleep, Oliver counted by 6s starting from 15. Thus the first few numbers he named were 15, 21, 27, 33...

The last number he named before he fell asleep was 363. How many numbers did Oliver name?

Yes, great!

 

so he counts in intervals of 6, from 15, to 363.

 

So 6 times x plus 15 = 363

 

6x + 15 = 363

 

6x  = 363-15 = 348

 

x = 348/6 = 58

 

That's all numbers after 15, so we add one to 58 so 59, I believe.
