What number goes in the box in the followng sequence 5 11 23 ? 95 191

Alina [70]

Answer:

Step-by-step explanation:

The number that should go after 23 is 47.

The pattern seems to be (n * 2) + 1, where n is the value of the previous number.

We start with the number 5:

(5 * 2) + 1 = 11

(11 * 2) + 1 = 23

(23 * 2) + 1 = 47

... and so on

The pattern should continue as follows.

Hope this helps!
