Cross mutiply. 42*10= 420. 14*g= 14g
14g= 420
divide by 14 for both sides
14g/14= 420/14
g= 30
Check answer by using substitution method
42/30. Divide by 3 . 42/3= 14 , 30/3= 10
14/10 and 14/10 equal to each other by dividing 2.
14/2= 7 , 10/2= 5
7/5= 7/5
Answer: g= 30
12,800 is rounded to the nearest hundred
The recursive formula of the sequence is aₙ = aₙ₋₁ - 30
<h3>How to determine the
recursive formula of the sequence?</h3>
From the question, we have the following sequence that can be used in our computation:
67 ,37 ,7, -23, -53
In the above sequence, we can see that the 30 is subtracted from the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ - 30
The above represents the recursive rule
Hence, the recursive rule of the function is aₙ = aₙ₋₁ - 30
