1. Salt. Salt is considered one of the top home remedies for oral thrush as it helps destroying the habitat of the fungus. Also, in case of infection, salt can reduce the symptoms and be a quick cure. Dilute Â½ to 1 teaspoon of salt with 1 cup of warm water.
A recursive rule written with the formula of: $$a_n = r * a_{n-1}$$ Or as: $$a_n = a_{n-1} + d$$ And an explicit rule written with the formula of: $$a_n = a_1 + (n â 1)d$$ Or as: $$a_n = a_1 * r^{n-1}$$ My math teacher told me that every recursive rule can be written as an explicit rule too and I found that to hold true through all of the math problems I did for homework.
Therefore, explicit formula of the given geometric sequence is an = 3 * 4n â 1. Recursive and Explicit Formulas â Practice Problems Problem 1: First term of the sequence a1 = 24, common difference d = 10, find the recursive formula of the arithmetic sequence. Problem 2: First term of the sequence a1 = 9, common ratio r = 4, find the recursive formula of the geometric sequence.
