Answer 1

-5.6, -0.2, 5.2, 10.6

Explanation:

Answer 2

-5.6, -0.2, 5.2, 10.6

Explanation:

This is a geometric sequence so use its general equation to solve for the missing values.

aₙ = a₁ + d(n - 1)

aₙ is the nth after the first number you're trying to find.

a₁ is the first number.

d is your scaling value. (n-1) is just there to help you calculate the previous values.

You have the first and last number (the sixth number which is 16). Use those to find your scaling value then it's just plug and chugg after that.
