I understand than function decreases exponentially, then order of growth of this function is exponential with negative exponent. But what does it mean that order of growth decreases exponentially?
I don't understand what should i look for in this exercise:
Exercise 2.33 Find a recurrence describing a sequence for which the order of growth decreases exponentially for odd-numbered terms, but increases exponentially for even-numbered terms.
Could you provide several first items of such a sequence to let me understand the exercise?
