Step-by-step explanation:
If you want to find the 5th term of a sequence or any term you have to substitute n for the desired term in your case the result is the following
![a_{n}=2n\\a_{5}=2(5)\\a_{5}=10](https://tex.z-dn.net/?f=a_%7Bn%7D%3D2n%5C%5Ca_%7B5%7D%3D2%285%29%5C%5Ca_%7B5%7D%3D10)
Nickels is 0,05 of dolar - n
dimes is 0,1 o dolar -d
quarters is 0,25 of dolar -q
dimes =2nickels
d=2n
quarters=2dimes
q=2d=4n
12,5=n(0,05)+2n(0,1)+4n(0,25)
12,5=0,05n+0,2n+n
12,5=1,25n
n=10
q=4n=40
There are 40 quarters
Um maybe add some answers choices or a picture next time pls !!
