Welcome @challenger's to the 11th #code4bytes challenge!. Sorry for the long delay, but there was some personal stuff taking away my time which made me unable to come up with new challenges.

Given an array, figure out if the first derivative is strictly positive or not

[1, 3, 7, 15, 27, 44, 63, 86, 107, 134, 168]

Example: [2, 4, 7, 13] true [3, 10, 15, 21] false

Extra info Using a library or function like numpy and doing numpy.gradient() does not count.
