Find an explicit formula for h (n).
h(n) =

1 answer

To find an explicit formula for the function \( h(n) \), we can analyze the given recursion.

We start with the initial condition:

\[ h(1) = 96 \]

And the recursive definition:

\[ h(n) = h(n - 1) - 1 \quad \text{for } n > 1 \]

Let's calculate the first few terms to see the pattern:

  • For \( n = 1 \): \[ h(1) = 96 \]

  • For \( n = 2 \): \[ h(2) = h(1) - 1 = 96 - 1 = 95 \]

  • For \( n = 3 \): \[ h(3) = h(2) - 1 = 95 - 1 = 94 \]

  • For \( n = 4 \): \[ h(4) = h(3) - 1 = 94 - 1 = 93 \]

From these calculations, we can see that as \( n \) increases by 1, \( h(n) \) decreases by 1. This gives us a linear pattern.

To find a general formula, we note that \( h(n) \) decreases by 1 for each increment of \( n \). Therefore, for any \( n \), we can express \( h(n) \) in terms of \( h(1) \):

\[ h(n) = h(1) - (n - 1) \]

Substituting \( h(1) = 96 \):

\[ h(n) = 96 - (n - 1) \]

This simplifies to:

\[ h(n) = 96 - n + 1 \]

So,

\[ h(n) = 97 - n \]

Thus, the explicit formula for \( h(n) \) is:

\[ \boxed{97 - n} \]
