25.2 is your answer, it is basically a half of 50.4
Answer:
The recursive formula of the arithmetic sequence is
Step-by-step explanation:
A recursive formula designates the starting term, , and the nth term of the sequence, , as an expression containing the previous term (the term before it), .
Recursive formulas give us two pieces of information:
- The first term of the sequence
- The pattern rule to get any term from the term that comes before it
From the arithmetic sequence , the first term is -16 and the rule to get any term from its previous term is add -17.
Therefore, the recursive formula should look as follows:
First use pythagoras thereom to find AD ; 10^2 -8^2, square rooted. Then find DC , again using pythagoras thereom, 17^2-8^2, square rooted. Now you have AD and DC, use pythagoras thereom ; AD^2 + DC^2 = AC^2
I really don’t know do you have a picture that you can show me
