Question

Guess the rule and enter the missing number in the sequence. 23, 20, 17, 14,

Answer 1

Answer = 11

Rule: subtract by 3 every number in the series

Answer 2

11

subtract 3

Explanation:

The numbers are getting lower in value as you go,

So that means it is a subtracting sequence,

Take the first two numbers and subtract them,

23 - 20 = 3

So now subtract 3 from the others and see if it works,

20 - 3 = 17

17 - 3 = 14

14 - 3 = 11

11 is the missing number

Yep, it works,

Hence the sequence is to subtract three.
