It would be 26.6 as the answer
The foreign exchange rate is a rate at which one currency is exchanged for another, and it exists because not all currencies are worth the same. In short, money of one country is worth more than money of a different country.
Answer:
g(n) = -29×(-4)ⁿ⁻¹
Step-by-step explanation:
This the recursive formula of a sequence g :
g(1)=-29
g(n)=g(n-1)x(-4)
now ,we want to deduce the standard explicit formula of that sequence
It’s clear from the recursive formula (above) that :
_The common ratio = -4
_the first term = -29
Then
the standard explicit formula is : g(n) = -29×(-4)ⁿ⁻¹
7 i just squared root 49 because 49 is a perfect square
