Any number from -10 to -∞ would be correct. One example is -79.
A(n)=a(1)+d(n-1), d=a(16)-a(15)=-5-(-53)=48
a(15)=a(1)+d*(15-1),
-53=a(1)+48*(15-1),
a(1)=-53-48*14= -725
a(n)=-725+48(n-1)
Answer:
Each hour he fly 107.76 miles
Step-by-step explanation:
we know that
Charles Lindbergh flew 3,610 miles in 33.5 hours
To find out the unit rate, divide the total distance by the total time
so

therefore
Each hour he fly 107.76 miles
Add 40 to both sides
20x = 60
Divide by 20
Answer: x = 3
Jeff has $6.80.
