What is the initial value ?

• -3

• 3

• 0

• 20

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

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
