Answer:
Now we have: -13, 8, -5, 3, -2, 1
Step-by-step explanation:
This is a Fibonacci sequence.
though modified.
so a_n = a_(n-1) + a_(n-2)
with a_3 = -5,
a_4 = 3
a_3 = -5 = a_2 + a_1
a_4 = 3 = a_3 + a_2 = -5 + a_2
then a_2 = 3 + 5 = 8
then.
a_3 = -5 = a_2 + a_1 = 8 + a_1
a_1 = -5 - 8 = -13
We now have: -13, 8, -5, 3, ....
Now we can find a_5 and a_6
a_5 = a_4 + a_3 = 3 + -5 = -2
a_6 = a_5 + a_4 = -2 + 3 = 1
Now we have: -13, 8, -5, 3, -2, 1
