Answer:
4
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a is the first term and r the common ratio
Here r = 5 and a has to be found, thus
=
, so
= 15624
Multiply both sides by 4
15624a = 62496 ( divide both sides by 15624
a = 4

For the answer to the question above asking to<span> write an expression to model its age in dog years</span><span> for a dog that is 2 years old or older. If x is equal to human age
then the dog is 2 years older
X = human years
x + 2 = is for the dog age
