**Reiny**, Saturday, April 21, 2012 at 4:42pmSo in each case you would have 5 terms

AS:

a = 4, t(5) = a+4d = 324

4 + 4d = 324

4d = 320,

d = 80

the three missing terms are 84 , 164, 244

GS:

a = 4, t(5) = ar^4 = 324

r^4 = 81

r = ± 3

if r = 3, the three missing terms would be

12, 36, 108

if r = -3 , the three missing terms would be

-12 , +36, -108
