The given sequence is 30, 27.5, 25.
To find the next term, we need to determine the pattern.
- The first term is 30.
- The second term is 27.5, which is 30 - 2.5.
- The third term is 25, which is 27.5 - 2.5.
It appears that each term is decreasing by 2.5.
Continuing the pattern:
-
From 25, if we subtract 2.5, we get:
25 - 2.5 = 22.5.
Thus, the next term in the sequence is 22.5.
