Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
Therefore, the ninth term of the given sequence is -15.
Answer:
<h2>x = 3.1</h2>Step-by-step explanation:
<h3><u>To solve first take logarithm to both sides</u>
That's
<h3>But
<h3>So we have
<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3><u>Using the rules of logarithms</u>
That's
<h3>Rewrite the expression
That's
<h3>x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>Hope this helps you
