A sequence of 7 numbers <u>starts with 8</u>. The <u>second number</u> in the sequence <u>is unknown</u> and <u>may be positive or negative</u>. The <u>third</u> through seventh numbers are the <u>sum of</u> the <u>previous two numbers</u> in the sequence, and the <u>seventh number is 0</u>. 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.
