What is the next number in the sequence? 0.3,0.5,0.8,1.2,1.7,...
2.6
2.5
2.3
2.2

To find the next number in the sequence \(0.3, 0.5, 0.8, 1.2, 1.7, \dots\), we can start by identifying the differences between consecutive terms:

- \(0.5 - 0.3 = 0.2\)
- \(0.8 - 0.5 = 0.3\)
- \(1.2 - 0.8 = 0.4\)
- \(1.7 - 1.2 = 0.5\)

We see that the differences between terms are increasing by 0.1 each time.

If this pattern continues, the next difference will be:
- \(0.5 + 0.1 = 0.6\)

Thus, the next term in the sequence is:
- \(1.7 + 0.6 = 2.3\)

So, the next number is **2.3**.
