I hope you have a good day!
at the beginning of year 4, only 3 years have elapsed, the 4th year hasn't started yet, since it's at the beginning, so at the beginning of year 4 we can say only 4-1 years have elapsed.
![A=700\left( 1 + \frac{0.05}{1} \right)^{1\cdot 3}\implies A = 700(1+0.05)^3\implies A(4)=700(1+0.05)^{4-1} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill A(n)=700(1+0.05)^{n-1}~\hfill](https://tex.z-dn.net/?f=A%3D700%5Cleft%28%201%20%2B%20%5Cfrac%7B0.05%7D%7B1%7D%20%5Cright%29%5E%7B1%5Ccdot%203%7D%5Cimplies%20A%20%3D%20700%281%2B0.05%29%5E3%5Cimplies%20A%284%29%3D700%281%2B0.05%29%5E%7B4-1%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20A%28n%29%3D700%281%2B0.05%29%5E%7Bn-1%7D~%5Chfill)
A cause and effect relationship between two variables, A and B, is written A then B, or in formal logic: A => B (A implies B).
A number that has one of the two equal number is not 2
Since it's arithmetic we are adding the same number each time.
4, ____, ____, _____, 6
t1, t2, t3, t4, t5
Subtract 6-4 = 2
Subtract t5 - t1 = 4
divide 2/4 = 1/2 the common difference is 1/2, we are adding 1/2 each time.
4, 4.5, 5, 5.5, 6
The second term is 4.5
