Why is 50 in the middle of 1 and 2900? After watching this video, I hope you will be able to explain why and be able to find any value on a logarithmic scale.

Hi sir I have a question, what if We got a point line on y-axis (log graph), how do we know how much is that value (not like you have 3.14 than you find its position - i mean we see a point and then how to find that point's value) ?
Thank you very much
Have a good day sir
