Which sequence matches the recursive formula? an=2an-1+5, where a1=5. A) 5,10,15,20 B) 5,15,35,75. C)5,15,25,35. D) 5,20,35,40

The recursive formula
means that, to compute the next value, you have to double the previous one and then add 5.
So, we start with 5. To get the second term, we double it and add five, so we have
Next, we will double 15 and add 5:
So, the answer is B, because it's the only option starting with 5,15,35.
Just to check, let's compute the last step:
Which confirms option B
12.5 kilometers per liter
well, an hour has 60 minutes, that means 10+10+10+10+10+10 minutes.
we know she can do ½ mile in 10 minutes, so in an hour, she'll be doing
½+½+½+½+½+½ miles, and you know how much that is.
