in triangle abc shown below, side ab is 10 and side ac is 8:

triangle abc with segment joining point d on segment ab and point e on segment ac.

which statement is needed to prove that segment de is parallel to segment bc and half its length?

don't know sorry bru

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
