The sum if the geometric sequence given by:
an=-2(3)^(n-1)
will be:
when:
n=1
an=-2
when n=2
a2=-6
when n=3
a3=-18
when n=4
a4=-54
when n=5
a5=-162
when n=6
a6=-486
when n=7
a7=-1458
when n=8
a8=-4374
thus the summation of the term will be:
Sn=(-4374+-1458+-486+-162+-54+-18+-6+-2)
Sn=-6560
the answer is -6560

Answer:
a = 3
Step-by-step explanation:
When you add the given value for a with 7, the resulting answer must be less than 11.
In this case, if: a = 3
Plug in 3 for a in the equation:
7 + a < 11
7 + 3 < 11
10 < 11 (True).
A) a = 3 is your answer.
