Problem 3: Consider the pattern shown below. The square grid that is 3 units long is made from 24 unit-long segments. 1 unit long 2 units long 3 units long a) How many segments are required to make a square grid that is 10 units long? b) Write a recursive formula for the number of segments required to make a square grid that is n units long. Show and/or explain how you got your answer. c) Write an explicit formula for the number of segments required to make a square grid that is n units long. Show and/or explain how you got your
