Question 6:
   The output of the program is: 102

   Let a(0) = 2
   Since a:= a + 4
   therefore a(1) = 2 + 4x1
   a(2) = a(1) + 4
   = 2 + 4 + 4
   = 2 + 4x2
   a(3) = a(2) + 4
   = 2 + 4x2 +4
   = 2 + 4x3
   a(n) = 2 + 4xn where n is an integer

   Since a(n) > 99, 2+4n >99
   n > 24.25
   n= 25
   Therefore a(n) = 2 + 4x25
   = 102


   Question 7:
   The output of the program is: 36

   When s=0, h=1, k=3, s= 0+1+3 = 4
   k=2, s=4+1+2 = 7
   k=1, s=7+1+1 = 9

   h=2 k=3, s=9+2+3 =14
   k=2, s=14+2+2=18
   k=1, s=18+2+1=21

   h=3 k=3, s=21+3=3=27
   k=2, s=27+3+2= 32
   k=1, s=32+3+1=36
