a. Recall that a geometric sequence is a sequence of the form a, ar, ar2, ar3.At the MATLAB command prompt (not in an M-File), create a for loop that prints the first seven terms of this sequence when r= and a=1. Include the output in your word document. works! Include the code for your M-File in your Word document. seven terms of the geometric sequence when r=1/4. Include the output and the code you b. Create a new M-File named "geomSeq" with the loop above. Be sure to test it to make sure it c. Modify your M-File so that it accepts the value of r as an argument. Use this to find the first used in your Word document
