Question 3999
 32, -48, 72, -108, . . .
 is a geometric series with common ratio
 r = -48/32 = 72/-48 = -108/ 72 = -3/2

 Let a1 = 32, the general term an of the sequence as
 an = a1 r^(n-1) for n>= 1.

 Hence, the next two terms are a5 = -108 * (-3/2) = 162,(= 32*(-3/2)^4)
 and a6 = 162 * (-3/2) = -243 (= 32*(-3/2)^5)

 Forget another wrong answer.
