What number comes next in the following sequence?
3, 3.5, 4.5, 6, ?

Correct option is C

Step 1: Find the differences between consecutive terms:
1. 3 to 3.5 → Difference = +0.5
2. 3.5 to 4.5 → Difference = +1.0
3. 4.5 to 6 → Difference = +1.5
Step 2: Identify the pattern of differences:
The differences are increasing by 0.5 at each step:
· +0.5 → +1.0 → +1.5 → +2.0 (next step).
Step 3: Add the next difference to the last term:
· Last term = 6
· Next difference = +2.0
6 + 2.0 = 8
