Given the geometric sequence an = 4(6)n − 1, which of the following values for n lies in the appropriate domain for n?

The sequence is A(n) = 6 [5 ^ (n-1) ]

Although, the formula may be applied to negative, zero and positive numbers, it does not make sense to talk about the -1 or zero term.

Ther first term is A(1), where n = 1, then the answer should be n =1.

n = 1

Here you can see that you the formula may be applied, but this does not mean that  you can do it, because n = 1 is used to define the first term.

For n = -1, A(1) = 6 [5^-2] = 6/ 5^2

For n = 0, A(0) = 6[5^-1] = 6/5

For n = 1, A(1) = 6 [5^0] = 6

For n =2, A(2) = 6 [5^1] = 6*5

For n = 3, A(3) = 6[5^2] = 6*5^2 

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
