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.
a1 is the first term in the sequence. To find the explicit formula, you will need to be given (or use computations to find out) the first term and use that value in the formula. r is the common ratio for the geometric sequence. You will either be given this value or be given enough information to compute it.
