Answer:
<h2>3 + 4(n - 1)</h2>
Step-by-step explanation:
let r be the common differenc of the sequence
Term 12 - Term 7 = (12 - 7)r
then
47 - 27 = 5r
then
20 = 5r
then
r = 4
term 7 = term 1 + (7 - 1)r
then
27 = term 1 + 6r = term 1 + 24
then
Term1 = 27 - 24 = 3
<em><u>therefore </u></em>
the standard explicit formula of the sequence is :
term 1 + (n - 1)r = 3 + 4(n - 1)
Answer:
30,000
Step-by-step explanation:
5,000 in 6 months therefore 10,000 in one year and 30,000 in 3 years
So for this you need to set them equal to each other! 3x+100=5x-160
now you combine like terms and solve!
36 = 3^2 * 2^2
