How to solve a math problem
Understand the problem first.Then, find formulas and information to help you solve the problem.
Example: Farmer duck's farm starts with 5 ducks. At the 6th week there are 40 ducks.
How much ducks get added to the farm each
1. In mathematical terms the problem is asking the common difference of a arithmetic sequence.
2. To find the common difference of a arithmetic sequence you can use the formula a1+d(n-1) = an
where a1 is the first term which equals 5 and d is the common difference which we are solving for n is the number of the term which in this case is 6 and an is the value of the nth term which is 40. Plugging in this information we find that
5+d(5) = 40
5d + 5 = 40
-5 -5
5d = 35
d = 7 therefore our answer is 7
