The two negatives cancel out, so it would just mean 1+18, which is 19.

H(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}h(n)=−91⋅(− 7 1 ​ ) n−1 h, left parenthesis, n, right parenthesis, equals
Kruka [31]

Given:

h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}

To find:

The recursive formula.

Solution:

We have,

h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}

It is in the form of explicate formula of a GP, .i.e., a_n=ar^{n-1}.

Here, a=-91 and r=-\dfrac{1}{7}.

The recursive formula of a GP is

a_n=a_{n-1}\times r

Using this the recursive formula for given problem is

h(n)=h(n-1)\times (-\dfrac{1}{7})

Therefore, the required recursive formula is h(n)=h(n-1)\times (-\dfrac{1}{7}).

Josh bought some cases of water. Each case has 12 water bottles.
Akimi4 [234]
Hello!

Equation D. t = 12c shows how many bottles of water Josh bought.

Explanation:

The first three equations would NOT give you the answer, because if you divide, you'll find out how many bottles are in each case.

If you subtract and add, it'll also result in the wrong answer, so D is the right equation.
