Julia is saving money each week. At the end of the first week, she saves $10. At the end of the second week, she has a total of $25.She continues saving 515 each week. Which of the following is a correct way of mathematically describing the sequence? (1 point)f(1) = 10. f(x) = f(n-1) + 15. for > 1of(1) = 10. f(n) = f(n-1) + 10. for n > 1fin) = 10 + 15fim - 10 - 10

Respuesta :

For this problem we know that at the end of the first week she saves 10 so then we have:

[tex]f(1)=10[/tex]

Then at the end of the second week the total is 25 so we have:

[tex]f(2)=10+15=25[/tex]

She continues saving $15 each week. So then the best way to represent this situation is:

[tex]f(1)=10,f(n)=f(n-1)+15[/tex]

And the best option would be:

f(1)=10, f(n) = f(n-1)+15, n>1
