I WILL GIVE BRAINIEST!!!! Help!!!! 4. A stone nudged off the Royal Gorge Bridge near Cañon City, Colorado, falls 1053 feet before
hitting water. Because its speed increases as it falls, the distance it travels each second
increases. During the first second, it drops 16 feet. During the next second, it drops an
additional 48 feet. During the third second, it drops another 80 feet. The distances traveled
each second form an arithmetic sequence:
16, 48, 80, ...
Part I: How far does the stone fall during the 5th second? Find and use the explicit formula.
a. What is the first term of the sequence?
b. What is d, the common difference?
c. Write the explicit formula in function notation. Use f(n) = f(1) + (n - 1)d, where f(1)

Answer:

i need help with this to

Step-by-step explanation:

Answer:

First term = a= 16.

Common difference, d, = 32.

Answer for the fifth second is = 144 feet.

Step-by-step explanation:

This question is simply an Arithmetic Progression, AP,.

so, the 1st second represents the first term and so on.

for the common difference, you just subtract the first from the second term and confirm by subtracting the second from the third term and i got 32.
