3) An iterative method for finding the square root of a number A, denoted by A, is An A an+1 + Starting with ao = 3, use this method to compute 7, accurate to 3 decimal places. Note, you must write down ao, a, a2 ... etc, until you have this accuracy. 2 2an = = n=1 a) [6 n= n=1 a () b) 2/3n-1 c) 8 n=2 1 r n = (-3) n+1 5n-1 = Hint: Write out the first three terms, then factor.)
