1. Answer:83667

   Step-by-step explanation:

   Here first term, a = 3

   Second term = 9

   Common difference, d = 6

   Last term an = 999

   a+(n-1)d = 999

   3+(n-1)6 = 999

   -3+6n = 999

   6n = 999+3 = 1002

   n = 1002/6 = 167

   Sum of n terms = (n/2)(a+an)

   = (167/2)(3+999)

   = 83667
