Question

find the general term
an
for the geometric sequence
a1=−2
and
a2=6

Answer 1

the n is supposed to be lowered as well as the 2 and 1

Answer 2

first find common ratio-> r=next term / current term = 6/(-2)=..?
then just put it in general formula for n terms
\(a_n = a_1 r^{n-1}\)
a1 = 1st term =-2
