First what your going to do is add the ending number and the beginning number together getting 40. After adding these two number together, divide your total, which is 40, by 2. so 40/2 will be 20 as your answer.
Combine like terms. Like terms are terms that are completely the same, excluding coefficients.
6n^2-5n^2= 1n^2
1n^2+7n^2= 8n^2
Final answer: 8n^2
So basically the question wants to confuse by saying “6 months” which is half a year, right? Do everything normally until 4yrs and then write into compound interest formula but with n as 1/2 which is root.
