C.!!!!!!!!!!!!!!!!!!!!!!!
This sequence is:
a(n)=-11(-4)^(n-1)
The sum of the sequence is:
s(n)=-11(1--4^n)/(1--4)
s(n)=-11(1--4^n)/5
so for the first seven terms
s(7)=-11(1--4^7)/5
s(7)=-11(1+16384)/5
s(7)=-11(16385)/5
s(7)=-36047 B.
55+85=140
180-140=40
10x=40
divide by ten on each side
x=4
Answer:
