Question

What are the next two terms in the sequence:
7,2,5,-3,8,-11,_,_

Answer 1

its similar to a fibonacci sequence. It alternates positive to negative and uses the previous 2 terms.


7 - 5 = 2

2 + 3 = 5

5 -( 5 + 3) = -3

-3 + (8 + 3) = 8

8 - (8 + 11) = -11

-11 + ( 11 + 19) = 19

19 - ( 19 + 30) = - 30

Answer 2
