number 1 of 7: 8

number 2 of 7: ? can be positive (+) or negative (-)

i think the second number is -3

number 3 of 7: the sum of the first two numbers (8+?)

if the second number is -3 then the 3rd number in the sequence is 5

number 4 of 7: 3

number 5 of 7: 2

number 6 of 7: 1

number 7 of 7: 0

sum of all 7 numbers: 8
