The rule for the nth terms is: a_n=13n-5
Further explanation:
First of all we have to decide whether it is an arithmetic sequence or geometric sequence. It is decided based upon common difference or common ratio.
common difference is the difference between two consecutive terms of an arithmetic sequence while common ratio is the ratio between consecutive terms of a geometric sequence.
Here
Common difference:
As the common difference is same, the given sequence is an arithmetic sequence
The general formula for arithmetic sequence is:
Here
a1=8
d=13
The rule for the nth terms is: a_n=13n-5

Round 16.18 to 16.25
round 5.94 to 6.
Do 16.25 - 6, and you get:
10.25
Answer:
16km
Step-by-step explanation:
Is that the whole picture?
You might’ve taken the picture wrong because there should be a equation at the top
Using the Pythagorean theorem:
b = √(c^2 - a^2)
b = √(30^2 - 18^2)
b = √(900 - 324)
b = √576
b = 24 feet
