Consider the sequence(an)n≥1that starts1,3,5,7,9,...(i.e, the odd numbers in order).

(a) Give a recursive definition and closed formula for the sequence.

(b) Write out the sequence(bn)n≥2 of partial sums of (an). Write down the recursive definition for (bn) and guess at the closed formula.

(b) How did you get the partial sums?

Do expand-guess-verify technique for the following relationships, show step by step. Find closed-form formula for these recursive relationships. Estimate running time complexity (Big Oh) of the closed-form formulas – those also give you idea how “good” or “bad” original recursive algorithms are! f(1) = 5 f(n) = f(n-1) + 4 f(1) = 2 f(n) = 3f(n-1)

1. Write 3n + 1 Sequence String Generator function (1 point) In lab5.py complete the function sequence that takes one parameter: n, which is the initial value of a sequence of integers. The 3n + 1 sequence starts with an integer, n in this case, wherein each successive integer of the sequence is calculated based on these rules: 1. If the current value of n is odd, then the next number in the sequence is three times the current number...
