Technically you could answer this one by one, by substituting n with 1, 2, 3, 4, then 5. Like here:
A1=(-2)A1-1
=(-2)A0, then substituting A0 with -1...
=(-2)(-1)
Which would mean A1=2. Then..
A2=(-2)A2-1
A2=(-2)A1
A2=(-2)(2)
Which would mean A2=-4.
By repeating this process you'd eventually get A4..
A5=(-2)A4
if you did the steps right you'd get that A4 is -16..
A5=(-2)(-16).
Then simplify to get your answer.
Answer:
yes, but the assignment is not here
I am assuming that this question is asking much 30% of 500 is, which is 150.
Given the fact that 95 is on the right side of the line
the left side would be 85 in which you would
add 85 to 60 which would be 145
then subtract 145 from 180 and you'll get
35 degrees as your missing angle so
X = 35
