Def / 2d cuando d= -2, e=4 y f= -5​

-160

Step-by-step explanation:

(-2)(4)(-5)/2(-2)

-8(4)(-5)/2(-2)

-32(-5)/2(-2)

160/2(-2)

160/-1

-160

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
