Ahmad starts hiking at an elevation of -50 feet and then stops to the rest at the elevation of 85 ft. which expression represents in elevation from start to his resting place. 50-85. -50-85. -85-(-50). 85-50

50 + 80 = 130 So the answer would be |-85-(-50)|.

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

not sure but it may be b, as i said i'm not sure.
