    Answer:

    The next number to complete the sequence is 13

    Step-by-step explanation:

    The sequence of given data is the reducing number by the specific value and the add double of same number in the outcome.

    The difference between numbers

    -6-3 = -9

    12 -(-6) = 18

    4 – 12 = -8

    20 – 4 = 16

    The pattern if behaves as

    x-n

    x-2x

    According to given pattern new number should be

    x – 20 = -7

    x = -7 +20

    x = 13

    The next umber will be 13

    Answer:

    13

    Step-by-step explanation:

    From the sequence above the number has a negative sign,increasing and decreasing at rates not quite understandable unless a proper attention is paid.

    The sequence of the above data is the reducing number by the specific value and the add double of same number in the outcome.

    Take a look a this

    -6-3 = -9(the first number is subtracted from the second)

    12-(-6)=18

    4 – 12 = -8

    20 – 4 = 16

    From the above one can realize that the outcome of every single linear algebra having the -ve sign will increase by 1(that means +1 is added to the previous number with a negative sign.

    So to following the sequence, the next number will b -7

    According to given pattern new number should be

    x – 20 = -7

    x = -7 +20

    x = 13
