I have created a trend line regression resulting (within x/y chart) resulting with equation -.381x^2 - 3.6076x^1 + 39.792. Based on the data, an X value of 50, should return a Y predicted value near 30.5. However, you can see my result is near 222... My exponential math is rusty enough, that I'm not confident in exact format - but found similar formula elsewhere..
