Study Notes

  • Geometric sequences and geometric series are types of number patterns

Geometric Sequence

  • Defined as a sequence where each term results from multiplying the previous term by a constant, non-zero common ratio (r)
  • Example: 2, 6, 18, 54,... where r = 3

Formula

  • The formula to find the nth term ($t_n$) of a geometric sequence is: $t_n = ar^{n-1}$
    • $t_n$ represents the nth term
    • a represents the first term
    • r represents the common ratio
    • n represents the term number

Geometric Series

  • Defined as the sum of the terms in a geometric sequence
  • Example: $2 + 6 + 18 + 54 +...$

Sum to n terms

  • The sum ($S_n$) of the first n terms of a geometric series is: $S_n = \frac{a(r^n - 1)}{r-1}$, where $r \neq 1$
    • $S_n$ represents the sum of the first n terms
    • a represents the first term
    • r represents the common ratio
    • n represents the number of terms

Sum to infinity

  • The sum to infinity ($S_\infty$) of a geometric series is: $S_\infty = \frac{a}{1-r}$, where $|r| < 1$
    • $S_\infty$ represents the sum to infinity
    • a represents the first term
    • r represents the common ratio
  • The sum to infinity formula only applies if the absolute value of the common ratio (r) is less than 1

Examples

  • Finding the 10th term of the sequence 4, 12, 36,...:
    • a = 4, r = 3, n = 10
    • $t_{10} = 4 \cdot 3^{10-1} = 4 \cdot 3^9 = 78732$
  • Finding the sum of the first 8 terms of the sequence 3, 6, 12,...:
    • a = 3, r = 2, n = 8
    • $S_8 = \frac{3(2^8 - 1)}{2-1} = \frac{3(256 - 1)}{1} = 3 \cdot 255 = 765$
  • Finding the sum to infinity of the sequence $5, \frac{5}{2}, \frac{5}{4},...$:
    • a = 5, $r = \frac{1}{2}$
    • $S_\infty = \frac{5}{1-\frac{1}{2}} = \frac{5}{\frac{1}{2}} = 10$
