Answer:
= 39 - 10n
Step-by-step explanation:
There is a common difference between consecutive terms , that is
19 - 29 = 9 - 19 = - 10
This indicates the sequence is arithmetic with nth term ( expicit formula )
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 29 and d = - 10 , then
= 29 - 10(n - 1) = 29 - 10n + 10 = 39 - 10n
Answer:

Step-by-step explanation:
If r varies directly with the square of m and inversely as s,
then
where k is some constant
Given r = 12 when m = 6 and s = 4:
⇒
⇒ 
⇒ k = 
Therefore, substituting the found value of k into the original equation: 
Find r when m = 4 and s = 10:

⇒ 
⇒
