Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11

The sequence is a geometric and the next term is 729
<h3>What is a geometric sequence?</h3>
A geometric sequence is a type of sequence which goes from one term to the next by multiplying or dividing by the same value.
The number multiplied or being divided at each stage of a geometric sequence is known as the common ratio.
From the sequence given,
1, 3, 27, 81, 243,
We can see that the common ratio is gotten by multiplying a term by 3 or dividing the next term by 3.
The next term is 243 × 3 = 729
Thus, the sequence is a geometric and the next term is 729
