Answer:
The common difference of given AP is Option 2) -10.
Step-by-step explanation:
We are given the following information in the question:
First term of AP, a = 100
The sum of its first 6 terms = 5(the sum of its next six terms)
We have to find the common difference of AP.
The sum of n terms of AP is given by:
where a is the first term and d is the common difference.
Thus, we can write:
Thus, the common difference of given AP is -10.
<h2>
Option C is the correct answer,</h2>
Step-by-step explanation:
The distance of planet Jupiter from the Sun is approximately 7.8 x 10⁸ kilometers.
Distance from Jupiter to Sun = 7.8 x 10⁸ kilometers
The distance of planet Saturn from the Sun is 1.5 x 10⁹ kilometers.
Distance from Saturn to Sun = 1.5 x 10⁹ kilometers
Difference in distances = 1.5 x 10⁹ - 7.8 x 10⁸ = 15 x 10⁸ - 7.8 x 10⁸
Difference in distances = 7.2 x 10⁸ kilometers
