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.

range is infinite on both x and y axis positive and negative

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
