Answer:
an=13.5−2.5n
Step-by-step explanation:
To find the common difference
Take the end term and subtract the first term
8.5 -11 = -2.5
Take the third term and subtract the 3rd term to verify
6-8.5 = -2.5 check
The formula for an arithmetic sequence is
an = a1+d(n-1)
an = 11 -2.5(n-1)
Distribute
an = 11 -2.5n+2.5
Combine terms
an = 13.5 - 2.5n
You can solve an equation by using ten blocks
The obvious outlier is 68, very far from those other numbers which cluster around 26.
Question wants to fill in the blanks for the given statement.
"2 roots is called _______ radicals".
It seems that you are looking for specific name of the root for the given statement.
Name of the radical is identified by the index of the given radical.
If the index is 2 then we call it square root.
If the index is 3 then we call it cube root.
If the index is 4 then we call it 4th root.
Similarly if the index is "n" then we call it nth root.
In given statement, index is 2 so the answer will be <u>"square root"</u>
