The rule for sequence is:
Step-by-step explanation:
To write the function rule, we have to check first whether it is an arithmetic sequence or geometric sequence
So
We have to find the common difference first. Common difference is the difference between two consecutive terms of a arithmetic sequence.
So,
Here
The common difference is same so the sequence is an arithmetic sequence.
The explicit formula for an arithmetic sequence is:
Putting the values of d and a_1 we get,
Hence,
The rule for sequence is:

The absolute value of -27 is 27, so it is the same number
Answer:
Y=-3x+5
Step-by-step explanation:
Given:
The ratio of the measures of the three sides of a triangle is 
.
Its perimeter is 31.4 centimeters
To find:
The shortest side of the triangle.
Solution:
Let the measures of the three sides of a triangle are 
respectively (in cm).
Its perimeter is 31.4 centimeters.
On further simplification, we get
Divide both sides by 3.
Now, the sides of triangle are
Therefore, the length of the shortest side is 6.978 cm.
