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.
Example 3: Find the explicit formula of the following arithmetic sequence; 11, 17, 23, 29, 35, 41, 47,â¦ Solution: First term a1 = 11, common difference d = 17 â 11 = 6. Use nth term formula to find the explicit formula. an = a1 + (n â 1)d. an = 11 + (n â 1)6. an = 11 + 6n â 6. an = 6n + 5. Therefore, explicit formula of the given arithmetic sequence is an = 6n + 5. Example 4: Find the explicit formula of the following geometric sequence; 3, 12, 36, 108, 432,â¦
