Luke is drawing triangles when given three side lengths. Which of these side lengths could be the side lengths of a triangle? Choose all that are correct. A. 2 cm, 10 cm, 13 cm B. 1 cm, 10 cm, 8 cm C. 5 cm, 9 cm, 5 cm D. 3 cm, 4 cm, 5 cm E. 4 cm, 6 cm, 2 cm
I don't understand how to get the answer so if you answer could you please explain how you got your answer?

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

no i do not : ( what is it?
