The equation that models the sequence is: 6+6 each time.
Its a squared + xb squared = c squared so its 11 squared + 11 squared equals c squared. So I'm gonna take it down to the next step and say 11x11+ 11x11= c squared, then you end up with 121+121= c squared then you add those two and end up with 242= c squared, so then you find the square root of 242 so you should end up with 15.5 and the number goes on and on and on
To figure this out i would just dived 2.8 by 3 then multiply by two. I do not know if you must keep it as a fraction but this is the easiest way for me to do it
