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=1⁄3 and a=1. include the output in your word document. create a new m-file named "geomseq" with the loop above. be sure to test it to make sure it works! include the code for your m-file in your word document. modify your m-file so that it accepts the value of r as an argument. use this to find the first seven terms of the geometric sequence when r=1/4. include the output and the code you used in your word document.
