Find the sum of the first 8 terms of the following series, to the nearest integer.
motikmotik

Answer:

The sum of the first 8 terms will be:

  • \frac{1288991}{7776}

Step-by-step explanation:

Given the sequence

36, 30, 25, ...

A geometric sequence has a constant ratio and is defined by

a_n=a_0\cdot r^{n-1}

computing the common ratio

\frac{30}{36}=\frac{5}{6},\:\quad \frac{25}{30}=\frac{5}{6}

r=\frac{5}{6}

As the first element is

a_1=36

so the nth term will be:

a_n=a_0\cdot r^{n-1}

a_n=36\left(\frac{5}{6}\right)^{n-1}

Geometric sequence sum formula

a_1\frac{1-r^n}{1-r}

Plugin the values to determine the sum of the first 8 terms

n=8,\:\spacea_1=36,\:\spacer=\frac{5}{6}

=36\cdot \frac{1-\left(\frac{5}{6}\right)^8}{1-\frac{5}{6}}

=\frac{\left(1-\left(\frac{5}{6}\right)^8\right)\cdot \:36}{1-\frac{5}{6}}    

=\frac{36\left(-\left(\frac{5}{6}\right)^8+1\right)}{\frac{1}{6}}

=\frac{36\left(-\frac{390625}{1679616}+1\right)}{\frac{1}{6}}

=\frac{\left(1-\frac{390625}{1679616}\right)\cdot \:36\cdot \:6}{1}

=\frac{216\left(-\frac{390625}{1679616}+1\right)}{1}

=\frac{216\cdot \frac{1288991}{1679616}}{1}

=216\cdot \frac{1288991}{1679616}

=\frac{1288991\cdot \:216}{1679616}

=\frac{278422056}{1679616}

=\frac{1288991}{7776}

 Therefore, the sum of the first 8 terms will be:

  • \frac{1288991}{7776}
