7. You have 42 chickens on your farm. They are increasing at a rate in 25% per year. Write an equation and find the number of chickens you have after 3 years. SAW
Equation
Find the number of chickens you have after 3 years. SAW

73 or 74

Step-by-step explanation:42/4=10.5 so 31.5 + 42 is 73.5 but round up or down

, 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

, and for
