If it's proportional, then to find the constant just divide the y - value by the x - value.

Take the first point, (5.8, 5.8).

Divide 5.8 by 5.8 to get your constant of proportionality: r = 1.

3/2

Step-by-step explanation:

Given

t_1 = 96

$r = \frac{1}{4}$

Required

Find t4

The nth term of a geometric sequence is calculated as:

$t_n = t_1 * r^{n-1$

So:

$t_4 = t_1 * r^{4-1$

t_4 = t_1 * r^3

This gives:

$t_4 = 96 * \frac{1}{4}^3$

$t_4 = 96 * \frac{1}{64}$

Express as a single fraction

$t_4 = \frac{96}{64}$

$t_4 = \frac{3}{2}$

Hence, the 4th term is 3/2
