Answer:
-47
Step-by-step explanation:
To find the answer, you need to find the pattern.
Each term of the sequence is decreased by an odd number in a pattern of (-1, -3, -5, -7, -9, -11, -13...)
So:
2 - 1 = 1 (second term)
1 - 3 = -2 (third term)
-2 - 5 = -7 (fourth term)
-7 - 7 = -14 (fifth term)
-14 - 9 = -23 (sixth term)
-23 - 11 = -34 (seventh term)
-34 - 13 = -47 (eighth term)
