Question

Find the missing number 3,7,6,5,9,3,12,1,15,?

Answer 1

Answer:

-1

Step-by-step explanation:

when we check the alternative numbers, we can find that they are related.

ie, 3, 6, 9, 12, 15 (each number is got by adding 3 to the last number)

also 7, 5, 3, 1 (each number is got by subtracting 2 to the last number).

So the next number can be found by subtracting 2 from 1, which will be -1.
