Find the next number in the series 4 8 12 20 --?

Answer 1

32

Answer 2

To find the next number in the series 4, 8, 12, 20, we need to identify the pattern or rule governing the sequence. In this case, the pattern is that each number is the sum of the previous two numbers.

4 + 8 = 12, 8 + 12 = 20, and 12 + 20 = 32.

Therefore, the next number in the series is 32.

Answer 3

There is a "Fibonacci" like series is that each digit is the sum of the preceding two numbers:

4 + 8 = 12

8 + 12 = 20

So the series continues:

12 + 20 = 32

20 + 32 = 52

32 + 52 = 84

52 + 84 = 136

and so on.

What number do you want to be next?

Give me a number and I'll give you a polynomial so that putting in 1, 2, 3, 4 gives the values 4, 8, 12, 20 and putting in 5 gives the number you want.

Answer 4

32
