The recursive formula would be

$g_n=g_{n-1}\times 2$ .

The explicit formula given is in the form

$g_n=g_1 \times r^{n-1}$

We can manipulate this formula to find the initial value as well as the growth rate:

$g_n=g_1 \times r^{n-1} = g_1 \times r^n \times r^{-1}
\\
\\=g_1 \times r^n \times \frac{1}{r}
\\
\\=g_1 \times \frac{1}{r} \times r^n= \frac{g_1}{r}\times r^n$

Viewing our equation in this form, we know that
$\frac{g_1}{r} = 25
\\
\\\text{ and } r=2$

which tells us that g₁ = 50.

Since r = 2, we can write our recursive formula:

$g_n=g_{n-1}\times 2$
