d) a1=10, q= 2 i 1/2, n=6
e) a1= -2, q=-3, n=5
f) a1=-7, q=-1, n=15
g) a1=5, q=pierwastek z 2, n=9

n=6 a6=1/8*2^5 = 1/8*32=4
n=7 a7=25*1/5^6= 1/625
n=4 a4= 8*2/3^3 = 64/27
n=6 a6= 10*2i1/2^5= 15625/16=976 i 9/16
n=5 a5 = -2*(-3)^4 = -2*81 = -162
n=15 a15= -7*(-1)^14= -7
n=9 a9= 5* (pierw.z2)^8= 80
n=8 a8 = pier.z3 * (-pierw.z3/3)^7= -1/27.
