--------------
Step 1) Make a table
The x values represents the number of each number in the sequence and the y values represent the numbers in the sequence.
so
x ⇒ y
0 ⇒ -25
1 ⇒ -50
2 ⇒ -100
3 ⇒ -200
--------------
Step 2) find the pattern
The pattern is that each number in the sequence is calculated by multiplying the number before it by 2. We know the pattern in relation to to y but we need to find the pattern in relation to x.
