Maya wants to mark a length of 7 inches on a sheet of paper, but she does not have a ruler. she has pieces of wood that are 4 inches, 5 inches and 6 inches long. explain how she can use these pieces to mark a length of 7 inches?

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
