What is the missing number?​

Answer 1

Answer:

...................?

Answer 2

Answer:

28.5

Step-by-step explanation:

differences between 1.5 and 0.5 is 1

differences between 4.5 and 1.5 is 3.0

differences between 13.5 and 4.5 is 9.0

So, according to differences of 1 then 3 and 9 the next number will be 15 (3*1=3)

(3*3=9)

(3*5=15)

So, now the differences between 13.5 and the next number is 15

then we will add 13.5 and 15

hence, it will give us 28.5
