I'm not sure what you are looking for. If you want to know the total number of degrees that interior angles of triangles total, they add up to 180°.
Hope this helps! :)
The next 3 terms would be: -14, -17, and -20 (the pattern is your -3 each time) the 100th term would be -279 i think because there is 93 spots left after the first 7 terms, so 93 x -3 = -279
If I’m analyzing the question correct, you would pay 912 in total
X < -16 is the solution
Hope this helped
If m<2 is 18 then m<1 is 72
