of their market price becomes 3:7. What is the present market price rate of each
type of mushroom? Find it.

Step-by-step explanation:

For Part 3 Double-Displacement Reactions: For each of the double-displacement reactions, describe what happened in each well, including the colors of any products that formed. If a chemical reaction occurred, write a balanced equation for it. Then using the A, B symbols, write a general equation for a double-displacement reaction.

sodium phosphate – Na3PO4

silver nitrate – AgNO3

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
