You decide to write a code which will scan the surface and spot irregularities by adding and subtracting RGB values from nearby points to identify anything unnatural. For your code to work efficiently, you will effectively be computing the sum of the first four terms (i.e., the fourth partial sum) of the following alternating series: (-1)n+1-An n=1 The parameter ) needs to be chosen to be as small as possible (for computational efficiency purposes) while also ensuring that the absolute error on the sum of the first four terms is at most 0.001. What value of A do you choose? (Round your answer to exactly two decimal places.) 1 = Number
