To identify the sequence pattern, let's analyze the differences between consecutive terms:
1. ( -5 - 10 = -15 )
2. ( 25 - (-5) = 30 )
3. ( -35 - 25 = -60 )
4. ( 85 - (-35) = 120 )
5. ( -155 - 85 = -240 )
The differences between the terms are: -15, 30, -60, 120, -240.
It seems that each difference is multiplied by -2 to get the next difference:
1. ( -15 (-2) = 30 )
2. ( 30 (-2) = -60 )
3. ( -60 (-2) = 120 )
4. ( 120 (-2) = -240 )
Following this pattern, the next difference should be ( -240 (-2) = 480 ).
To find the next term in the sequence, we add 480 to the last term (-155):
-155 + 480 = 325
So, the next term in the sequence is 325.
