SOLUTION
In the Fibonacci sequence of:
T1,T2,T3,......
T3=T2+T1
T4=T3+T2
T5=T4+T3
And the sequence continues like that, the next term is a summation of the previous two.
So with this knowledge, we can find the first 20 terms of the sequence in
question.








Therefore, the first 10 terms are -9,-3,-12,-15,-27,-42,-69,-111,-180,-291.
