$\bf 7~~,~~\stackrel{7+6}{13}~~,~~\stackrel{13+6}{19}~~,~~\stackrel{19+6}{25}\qquad \impliedby \qquad \textit{common difference "d" is 6}$

we know all it's doing is adding 6 over again to each term to get the next one, so then

$\bf \stackrel{\textit{Recursive Formula}}{\stackrel{\textit{nth term}}{f(n)}~~=~~\stackrel{\textit{the term before it}}{f(n-1)}~~~~\stackrel{\textit{plus 6}}{+~~~~6}}$

now for the explicit one

$\bf n^{th}\textit{ term of an arithmetic sequence} \\\\ a_n=a_1+(n-1)d\qquad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ d=\textit{common difference}\\[-0.5em] \hrulefill\\ a_1=7\\ d=6 \end{cases} \\\\\\ a_n=7+(n-1)6\implies a_n=7+6n-6\implies \stackrel{\textit{Explicit Formula}}{\stackrel{f(n)}{a_n}=6n+1} \\\\\\ therefore\qquad \qquad f(10)=6(10)+1\implies f(10)=61$

Taylor buys 5 ounces of tea leaves for 2.35 .A this rate ,how much money does she need to buy 12 ounces of tea leaves

finlep [7]

Answer:

$5.64

Step-by-step explanation:

To solve this, I'd first find the cost of 1 ounce, then scale it up to 12. So since it's $2.35 for 5 oz, you just need to divide the two numbers.

2.35/5 = 0.47

So it costs 47 cents per ounce, which you want 12 of.

0.47 x 12 = 5.64 for 12 ounces.

I hope this helps!
