Function Specification Details

Hide Function Specifications

Some of these functions will need loops. Some are count$-$driven and will require a for loop and others are condition$-$driven and will require a while loop. You must decide based on the problem description.

You must not use list comprehensions, continue or break statements within your wh$1$le loops or wh$1$le True as it is important you demonstrate you understanding of how to write a condition to control a loop.

Part $1$

An arithmetic sequence is defined by a starting value a and an increment b$,$

The terms of the sequence are:

For example, when $a=6$ and $b=10,$ the resulting sequence is

$6,16,26,36,$dots

Design a function called get$\_$sequence that takes three integer values representing the starting value, the increment and the maximum value to append to the result sequence. The function should return a string with the elements of the sequence separated by commas.

Examples:

The call get$\_$sequence $(2,5,32)$ should return the string: $\text{'}2,7,12,17,22,27,32\text{'}$

The call get$\_$sequence $(2,5,31)$ should return the string: ${?}^{\text{'}}2,7,12,17,22,27\text{'}$

The returned string must be formatted exactly as demonstrated in the examples, with commas between values and no additional white space or trailing commas.

NOTE: you may not use the following Python String functions: join, strip, rstrip, $1$strip
