Find the sum of the first five terms using the geometric series formula for the sequence left curly bracket 1 half comma space m
MatroZZZ [7]

Answer:

\bold{\dfrac{11}{2 }}

Step-by-step explanation:

Given the geometric series:

\{\dfrac{1}2, -1, 2, -4,  ..... \}

To find:

Sum of series upto 5 terms using the geometric series formula = ?

Solution:

Formula for sum of a n terms of a geometric series is given as:

S_n=\dfrac{a(1-r^n)}{1-r} \ \{r

a is the first term of the geometric series

r is the common ratio between each term (2nd term divided by 1st term or 3rd term divided by 2nd term ..... ).

Here:

a = \dfrac{1}{2}

r = \dfrac{-1}{\dfrac{1}{2}} = -2

n=5

So, applying the formula for given values:

S_5=\dfrac{\dfrac{1}2(1-(-2)^5)}{1-(-2)} \\\Rightarrow S_5=\dfrac{1-(-32)}{2 \times 3} \\\Rightarrow S_5=\dfrac{1+32}{6} \\\Rightarrow S_5=\dfrac{33}{6} \\\Rightarrow \bold{S_5=\dfrac{11}{2}}

So, the answer is

\bold{\dfrac{11}{2 }}
