Answer:
around 917
Step-by-step explanation:
The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)
t - time, d - distance, v - speed
![d=39 \ mi \\ v=26 \ \frac{mi}{h} \\ \\ t=\frac{39}{26}=\frac{3 \times 13}{2 \times 13}=\frac{3}{2}=1.5 \ [h]](https://tex.z-dn.net/?f=d%3D39%20%5C%20mi%20%5C%5C%0Av%3D26%20%5C%20%5Cfrac%7Bmi%7D%7Bh%7D%20%5C%5C%20%5C%5C%0At%3D%5Cfrac%7B39%7D%7B26%7D%3D%5Cfrac%7B3%20%5Ctimes%2013%7D%7B2%20%5Ctimes%2013%7D%3D%5Cfrac%7B3%7D%7B2%7D%3D1.5%20%5C%20%5Bh%5D)
It will take
1.5 h.
7•x=x-15
I think this would work, if I understood what you were saying correctly.
