5. Find the first, fourth, and tenth terms of the arithmetic

Lubov Fominskaja [6]

The first, fourth and tenth terms of the arithmetic sequence is $-6, -\frac{27}{5}$ and $-\frac{21}{5}$

Explanation:

The given rule for the arithmetic sequence is $A(n)=-6+(n-1)(\frac{1}{5} )$

We need to determine the first, fourth and tenth terms of the sequence.

To find the first, fourth and tenth terms, let us substitute $n=1,4,10$ in the general rule for the arithmetic sequence.

To find the first term, substitute $n=1$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(1)=-6+(1-1)(\frac{1}{5} )$

$A(1)=-6+(0)(\frac{1}{5} )$

$A(1)=-6$

Thus, the first term of the arithmetic sequence is -6.

To find the fourth term, substitute $n=4$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(2)=-6+(4-1)(\frac{1}{5} )$

$A(2)=-6+(3)(\frac{1}{5} )$

$A(2)=\frac{-30+3}{5}$

$A(2)=\frac{-27}{5}$

Thus, the fourth term of the arithmetic sequence is $-\frac{27}{5}$

To find the tenth term, substitute $n=10$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(10)=-6+(10-1)(\frac{1}{5} )$

$A(10)=-6+(9)(\frac{1}{5} )$

$A(10)=-6+\frac{9}{5}$

$A(10)=-\frac{21}{5}$

Thus, the tenth term of the arithmetic sequence is $-\frac{21}{5}$

Hence, the first, fourth and tenth terms of the arithmetic sequence is $-6, -\frac{27}{5}$ and $-\frac{21}{5}$

Evan was carrying forward a balance of $300 from the previous month. His annual interest rate is 30%. Use computation to determi

sattari [20]

<u>Answer</u>:

The interest charged for this month is $7.5

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

Given:

Principal = $300

Interest = 30%

Time = 1 month

To Find:

The interest charged for this month = ?

Solution:

we know that the interest charged = $principal \times \text {Interest rate} \times time$

1 month can also be written as $\frac{1}{12}$

Substituting the values,

interest charged:

=> $300 \times 30% \times \frac{1}{12}$

=> $300 \times \frac{30}{100} \times \frac{1}{12}$

=> $300 \times \frac{3}{120}$

=> $\frac{900}{120}$

=> $\frac{30}{4}$

=> $\frac{15}{2}$

=> 7.5
