To find that out, we divide 266 by 3,which we could then get 88.67,thus between 1 and 266 there would be 3 multiples, we then minus the number by 3 as multiples is before 10. Thus, the answer is 85
The lowest "multiple of 3 number" between 10 and 226 is 12. The highest "multiple of 3 number" between 10 and 226 is 225. Use the formula of arithmetic sequence to find how many multiples of 3. [tex]\boxed{Un = a + d(n-1)}[/tex]
Un stands for the nth term of the sequence. a is for the first term. d is for the difference, in this case the difference is 3 because we're using multiples of 3. What we're looking for is n.
