It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.
8 7 5 2 -2 .1.2.3..4 Therefore, -2 is the next number.
The next number in the series will be 66. The next number is found by adding the two previous numbers. (2+7=9, 9+7=16, etc...)
The sequence alternates between positive and negative numbers, with each number being multiplied by -2 to get the next number. Starting with 7: 7 * -2 = -14, -14 * -2 = 28, 28 * -2 = -56. Therefore, the next number would be -56 * -2 = 112.
Divide by 2, add 2. So, the next number is 7
The next number is 30+7 = 37.
22
7.
The next number is 2.
Either 7, 2 or 27?
5
11
It is 37
