To convert dog years to human year, count 21 human years for the first two dog years and then 4 human years per dog year for each dog year thereafter. write an expression that represents the human age of a dog that is y dog years old, where y is greater than 2.

Hello mate!

We know that Y is greater than 2, then we can write Y as X + 2, where X is a number greater than 0.

Then X is the number of years that passed since the second year.

We know that the first two years are equivalent to 21 years, and each year since then is equivalent to 4 human years

Then the equation that represents the dog's age in human years is

A(X) = X*4 + 21

where we used X instead of Y, because we change the first two years of Y for that constant  21.

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
