N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q

The explicit formula of the arithmetic sequence:

d - common difference
We have the recursive formula of an arithmetic sequence:

Therefore we have:

Substitute:

<h3>Answer: aₙ = 7 - 3n</h3>
Answer: w = 61
Step-by-step explanation:
If the wall is 456 cm then the carpenter has already used up 334 cm of the wall on the other book cases. So 456-334 = 122 and since both of the bookcases are going to be the same width you divide 122 by 2 which gives you 61. Hope this helps :).
let's firstly convert the mixed fractions to improper fractions and then divide.
