The third nth term in 3n+2 is 11
1st way= Round your SUM to the closest. Example: 44 is close to 40 since its not 45 yet.
You would have to find Circumference
the problem would be set up as 6+(7*x)=41
first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41
7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9
so x =5.9
