¿Qué significado tiene un rango de notas 8,4 respecto de las notas de otro alumno cuyo rango es 4,8? ¿Podemos decir que notas están más dispersas? ¿Podemos decir cuáles son mejores?

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

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

but which class are u may know that first
