Answer:
=
+ 2.5
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 2.5
The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus
=
+ 2.5 ← recursive formula with a₁ = 3
Dividing both sides by rt,

9/2+5/78
9/2+47/8
83/8
10 3/8
decimal form 10.375.
hope this helps!
Answer:
4
Step-by-step explanation:
- 9×2-14(n=9)
- 18-14
- 4 is answer
Assuming that the diver descended at a consistent rate throughout the entirety of his dive, the diver's average descent distance each hour is 275.
To find this average descent distance divide the total distance by the total time.
total distance = 825
total time = 3
825/3 = 275
