Write an
explicit formula for An, the nth term of the sequence 20, 30, 40,

= 10n + 10

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence

d = 30 - 20 = 40 - 30 = 10

This indicates the sequence is arithmetic with explicit formula

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 20 and d = 10, thus

= 10 + 10(n - 1) = 10 + 10n - 10 = 10n + 10

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
