What is the common ratio of the geometric sequence below 10,15,22.5,33.75

You divide each member by the one before it

Explanation:

You'll find that the answer  r = 1.5  ( r  for ratio)

The first term is called  u∧0 = 10

So the  n th term is called  u n − 1  and it takes n − 1  multiplications to get there from u 0 , so:

n th term =  u n  − 1  = u 0 ×  r n − 1

Or, in your case: n th term  = u n − 1 = 10 × 1.5 n − 1

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
