expresión -[p -(q + -r)],para p = -3, q = 2 yr = -4

6

Step-by-step explanation:

[-3 -(2 + -4)]

orden distributiva

-3 * 2= -6

-3 * -4= 12

-6 + 12= 6

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
