Find the common ratio and an explicit form in each of the following geometric sequences.
c.4 / 3,2 / 3,1 / 3,1 / 6 ,

The common ratio is and the explicit form is  for all n≥1.

Step-by-step explanation:

The general form of a geometric sequence is    ,   for all  n≥1, where r≠0   is the common ratio and is the first term  of the sequence.

From the problem we know the first term is a= ,   so we only need to calculate   r.  We  know that is the second  term of the sequence, so  we can replace and   a into our formula and find the value of r, so we have  for n=2

so the explicit form is   for all  n≥1, where

We can check the general formula by substituting the values into the equation.

We can conclude that the explicit form of the geometric sequence is  for all n≥1, and  the common ratio is  .

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
