given series.
6.25, 9, 12.25, 16, 20.25, 25, 30.25,?​

Answer 1

36

alternatively 0.25 is added.

9-6=3

12-9=3

16-12=4

20-16=4

25-20= 5

30-24= 5

so 3 after 4 after 5 after 6

so we should add 6 to 30

so answer is 36

Answer 2

The next number is 36.

Step-by-step explanation:

Consider the provided series.

6.25, 9, 12.25, 16, 20.25, 25, 30.25,?​

Observe the pattern.

9-6.25 = 2.75

12.25-9 = 3.25   (2.75+0.5=3.25)

16-12.25  = 3.75  ( 3.25+0.5=3.75)

20.25-16  = 4.25  ( 3.75+0.5=4.25)

25-20.25  = 4.75  ( 4.25+0.5=4.75)

30.25-25  = 5.25  ( 4.75+0.5=5.25)

Add 0.5 in previous difference then add to the previous number.

5.25+0.5=5.75

The next difference should be 5.75.

30.25+5.75=36

Hence, the next number is 36.
