What are the first five partial sums of the arithmetic sequence an = 0.05(n – 1) – 0.6?

Gnoma [55]

The sum of the arithmetic sequence given by
<span>an = 0.05(n – 1) – 0.6
will be given by:
a1=0.05(1-1)-0.6=-0.6
a2=0.05(2-1)-0.6=-0.55
a3=0.05(3-1)-0.6=-0.5
a4=0.05(4-1)-0.6=-0.45
a5=0.05(5-1)-0.6=-0.4
thus the summation will be:
-0.6+(-0.55)+(-0.5)+(-0.45)+(-0.4)
=-2.5
hence
S5=-2.5</span>

Answer now!!! Please!!! (Math)

Serggg [28]

<u>Answer:</u>

The correct answer option is $\frac{25}{9}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to evaluate it when $a = 5$ and $k = -2$ :

$[\frac{3^2a^{-2}}{3a^{-1}} ]^k$

Substituting the given values of $a$ and $k$ to get:

$[\frac{3^2(5)^{-2}}{3(5)^{-1}} ]^{-2}$

$\frac{3^{(2\times -2)}.5^{(1\times-2)}}{3^{(-1\times-2)}.5^{(2\times-2)}}$

$\frac{3^{-4}.5^{-2}}{3^{-2}.5^{-4}}$

$3^{-2}.5^2$

$\frac { 1 } { 3 ^ 2 } . 2$

$\frac { 1 } { 9 } . 2 5$

$\frac { 2 5 } { 9 }$
