Update 3n_plus_1.py (#7966)
* Update 3n_plus_1.py

1. Minor issue with ValueError message: Given integer should be positive, not greater than 1, as 1 is allowed.
2. += calls underlying list extend method which might be slower. Calling apend seems more appropriate.

Dodecahedron surface area and volume (#6606)
* Hexagonal number sequence 

A hexagonal number sequence is a sequence of figurate numbers where the nth hexagonal number hₙ is the number of distinct dots in a pattern of dots consisting of the outlines of regular hexagons with sides up to n dots, when the hexagons are overlaid so that they share one vertex.

This program returns the hexagonal number sequence of n length.

For the better understanding of time taken. (#6583)
* For the better understanding of time taken.

In this change I have initialized a variable p with the value of (1e9+7) and then took the modulus of process time with it . This modification gives better time taken by the process . Firstly it was giving answer in the exponential now it gives in the integer form.
