For the sequence given by a_n=2n+4 , answer the following: a. write the first five terms of the sequence b. find the sum of the first 20 terms

a) = 2(n) + 4

= 2(1) + 4   = 6

= 2(2) + 4 = 8

= 2(3) + 4 = 10

= 2(4) + 4 = 12

= 2(5) + 4 = 14

6, 8, 10, 12, 14

b)

Solve for last term:   = 2(20) + 4 = 44

   = 25 * 20

   = 500

= 500

correct answer:

i^31 = -i
