Answer:</h2>
n = 1
<h2>
Explanation:</h2>
Here we have the following Geometric Sequence:

Where:

The first term occurs when
. Next the second term occurs when
, the third term when
and so on. Therefore, the appropriate value of n that lies on the domain for n is
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
Step-by-step explanation:
Let,
Weight of one large bead = x
Weight of one small bead = y
According to given statement;
12x+8y=88 Eqn 1
5x+2y=25 Eqn 2
Multiplying Eqn 2 by 4

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 8

Putting x=1.5 in Eqn 1

Dividing both sides by 8

Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
