In how many ways can a single straight line cut a regular hexagon in half?

6. Since I think this answer is best explained visually, I've included an image showing all of those lines (often called the symmetry lines of a hexagon)

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

can you rephrase the question ? it is unclear : -)
