Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 45, 15, 5, ... This is (geometric/arithmetic) sequence and the (common ratio/ common difference) is equal to ___ (enter number)​

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
