I have array of numbers. After one number of these,the progress is big and numbers after that start to increase rapidly. How can I find this specific number? for example:we have 2,4,7,8,6,19,26,38,50 and from 2 to 6 the progress is small but from 19 the progress is big, the answer is 19.
How can I find this number in C or C#?
