What is the recursive rule for the sequence? 4.4, 5.8, 7.2, 8.6, 10, … an=an−1−1.4 , where a1=4.4an=an+1+1.4 , where a1=4.4an=an+1−1.4 , where a1=4.4an=an−1+1.4 , where a1=4.4

Answer : option d

4.4, 5.8, 7.2, 8.6, 10, …

First we find the common difference between two terms

5.8 - 4.4 = 1.4

7.2 - 5.8 = 1.4

8.6 - 7.2 = 1.4

10 - 8.6 = 1.4

So common difference is 1.4

To find recursive rule, we add the difference with previous term

Recursive rule is

a1 is the first term so a1= 4.4

d is the difference = 1.4

So recursive rule is

, where a1 = 4.4

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
