Geometric 61524

Determine the first term and quotient in the geometric sequence: a4 = -8 / 3; a6 = -32 / 3

Correct answer:

q =  2
a1 =  -1/3

Step-by-step explanation:

a4=8/3=38=2322.6667 a6=32/3=332=103210.6667  a6 = q2   a4  q=a6/a4=(10.6667)/(2.6667)=2
a4 = a1 q3  a1=q3a4=23(2.6667)=31=0.3333
