To find the common ratio in a geometric sequence, u divide the second term by the first term. 20/80 = 1/4 <== common ratio
Terms are found in a geometric sequence by multiplying each number by the common ratio to get to the next number.
start with 80
80 * 1/4 = 80/4 = 20
20 * 1/4 = 20/4 = 5
5 * 1/4 = 5/4
5/4 * 1/4 = 5/16 <===
5/16 * 1/4 = 5/64 <===
5/64 * 1/4 = 5/256 <===

Depending on the way the problem is communicated, your first listed item is usually on the top, while your second is placed on the bottom, in the case of a fraction. In the case of a colon, the left is your first unit and the right is your second.
<u>Answer:</u> logₓ 8
<u>Step-by-step explanation:</u>
5 logₓ2 - logₓ4
= logₓ2⁵ - logₓ4
= logₓ32 - logₓ4
= logₓ(32/ 4)
= logₓ 8
