What is a geometric sequence

a geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying a constant called the common ratio which is R

Step-by-step explanation:

in a geometric series you multiply the n th term by a certain common ratio are in order to get (n+1)th term in arithmetic series you can add the common difference D to the n th term in order to get (n+1) th term.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
