A sequence of 7 numbers starts with 8. The second number in the sequence is unknown and may be positive or negative. The third through seventh numbers are the sum of the previous two numbers in the sequence, and the seventh number is 0. What is the sum of the 7 numbers?
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
btw please dont take my word for it this is probably wrong i think my thinking was right but i made a mistake somewhere. there wasnt enough data for me to wrap my mind around. i hope you find the answer soon.
