Consider the sequence (an)n≥0 which begins 3,8,13,18,23,28,... (note this means a0 = 3) (a) Find the recursive and closed formulas for the above sequence. (b) How does the sequence (bn)n≥0 which begins 3,11,24,42,65,93,... relate to the original sequence (an)? Explain. (c) Find the closed formula for the sequence (bn) in part (b) (note, b0 = 3). Show your work.

Ques.3: Consider the addition of n-bit numbers on a machine of width n-bits. Specifically, the two n-bit 2’s complement numbers A=an-1,an-2,…a1,a0 and B=bn-1,bn-2,…b-1,b0 are added to get the n-bit sum C=cn-1,cn-2,…c1,c0. Provide a Boolean function F (defined in terms of the input variables ai and bi and output variables ci, where 0 <= i < n ) that determines if an overflow has occurred in this addition – the function should be expressed in terms of input variables. F should...

3. Consider the following property: for any ε>0, there exists N∈N so that whenever n≥N,|u_n+1−u_n|<ε. What is the difference between this property and the definition of a Cauchy sequence? Find a convergent sequence which has this property. Find a divergent sequence which has this property. (Hint: can you think of a function f(x) which grows to infinity very slowly? Then try a_n=f(n).
