It's much easier to see the pattern if you represent them as fractions:
3.5 = 7 / 2
5.25 = 21 / 4
7.875 = 63 / 8
11.8125 = 189 / 16
The ratio between terms is 3/2 (or 1.5). Multiply the numerator by 3 and the denominator by 2 to get your next answer.
The next terms will be...
567 / 32 = 17.71875 <---

Write each number as a fraction: 7/2, 21/4, 63/8,...
You can see the numerator trebles and denominator doubles each time.
The 5th term is 567/32 = 17.71875
The 6th term is 1701/64 = 26.578125

The next number in the sequence is the previous number multiplied by 1.5.
In these sequencing problems try dividing the number by it's predecessor to see whether it's a simple multiplication.
