Study Notes
Binomial Theorem
- The formula for the binomial theorem is $(a + b)^n = \sum_{k=0}^{n} \binom{n}{k} a^{n-k} b^k$
- In the formula, 'n' represents the power to which the binomial expression (a + b) is raised
Binomial Theorem Applications
- The binomial theorem allows us to expand powers of binomial expressions, making it easier to calculate and simplify expressions
Arithmetic Series
- The sum of the first 10 terms of the arithmetic series 3, 7, 11, ... can be calculated using the formula $S_n = \frac{n}{2}(a + l)$, where 'a' is the first term, 'l' is the last term, and 'n' is the number of terms
Geometric Sequence
- The 8th term of the geometric sequence 2, 6, 18, ... can be calculated using the formula $t_n = ar^{n-1}$, where 'a' is the first term, 'r' is the common ratio, and 'n' is the term number
Arithmetic Sequence
- The common difference in the arithmetic sequence 4, 1, -2, ... is the constant difference between consecutive terms, which can be calculated by subtracting any term from its previous term
