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.
Now that we know what the two different types of sequences are, arithmetic and geometric, we can dive into what exactly explicit means, what the formulas for the different sequences are, and how we can apply them to identify specific terms. As mentioned, an explicit formula is a formula we can use to find the nth term of a sequence. In the easiest definition, explicit means exact or definite. The formula is explicit because as long as it's applied correctly, the nth term can be determined. Arithmetic and geometric sequences have different explicit formulas. Explicit Formula for an Arithmetic Sequence. The explicit formula for an arithmetic sequence is a sub n = a sub 1 + d(n-1)
