Question

Insert the missing number: 6 17 37 10 10 25 12 32 ?

Answer 1

Answer: The missing number is 15.

6 + 11 = 17

17 + 20 = 37

37-27=10

10 - 0 = 10

10 + 15 = 25

25 - 13 = 12

12 + 20 = 32

32 - 17 = 15

Hence the missing number is 15 which is found by addition or subtraction of numbers in the sequence of series.It does not follows any prescribed pattern but the sequence is formed by adding or subtracting the numbers according to the numbers in the sequence.

Answer 2

Answer:

70

Step-by-step explanation:

The first numbers are all divisible by 2.  Assign all first numbers value of a, the second numbers value of b, the third numbers value of z and apply this formula to find the final number: z = (b * 2) + (a / 2)

For example the first line is 6, 17, and 34.  So 37 = (17 * 2) + (6 / 2)

Simplified that's 37 = 34 + 3

The second line of 10, 10, 25 also works using the same formula.

25 = (10 * 2) + (10 / 2), or

25 = 20 + 5

So in this case the final line is 12 and 32.  Plugging them into the formula I wrote out the answer is as follows:

z = (32 * 2) + (12 / 2)

z = 64 + 6

z = 70
