Question

Look at this series: 1.5,3,5.5,9,13.5,19,25.5,33,... What number should come next?​

Answer 1

Answer:

41.5

Explanation:

1.5,3,5.5,9,13.5,19,25.5,33

(3-1.5=1.5),(5.5-3=2.5),(9-5.5=3.5),(13.5-9=4.5),(19-13.5=5.5),(25.5-19=6.5),(33-25.5=7.5)

So looking at the pattern next number is 33 + 8.5 = 41.5

Answer 2

Answer:

41.5

Explanation:

3-1.5=1.5

5.5-3=2.5

9-5.5=3.5

13.5-9=4.5

19-13.5=5.5

25.5-19=6.5

33-25.5=7.5

After every equation the number is added is increasing by 1 so next step will be (33+8.5=41.5)
