SOLUTION: Write the first 5 terms of the sequence: a_(1)=1 a_(2)=0 a_(n)= a_(n-1)-a_(n-2) For a_(3) I got -1 but when I try solving for a_(4) I get -1 again, and for a_(5) I get 2.

Question 1108762: Write the first 5 terms of the sequence:
a_(1)=1
a_(2)=0
a_(n)= a_(n-1)-a_(n-2)
For a_(3) I got -1 but when I try solving for a_(4) I get -1 again, and for a_(5) I get 2.
Key:
a_(#) in words means "a sub #".

a%5B1%5D = 1

a%5B2%5D = 0

a%5B3%5D = a%5B2%5D - a%5B1%5D = 0 - 1 = -1

a%5B4%5D = a%5B3%5D - a%5B2%5D = -1 - 0 = -1

a%5B5%5D = a%5B4%5D - a%5B3%5D = -1 - (-1) = -1 + 1 = 0.



The first 5 terms are  1,  0, -1, -1,  0.
