Ms. Sheela visited a store near her house and found that the glass jars are arranged one above the other in a specific pattern.
On the top layer there are $3$ jars. In the next layer there are $6$ jars. In the $3^{rd}$ layer from
the top there are $9$ jars and so on till the $8^{th}$ layer.
On the basis of the above situation answer the following questions.
$(i)$ Write an $A.P$ whose terms represent the number of jars in different layers starting
from top . Also, find the common difference.
$(ii)$ Is it possible to arrange $34$ jars in a layer if this pattern is continued? Justify your
answer.
$(iii) (A)$ If there are $' n\ '$ number of rows in a layer then find the expression for finding the total number of jars in terms of $n$.
Hence find $S_8$.
OR
$(iii) (B)$ The shopkeeper added $3$ jars in each layer. How many jars are there in the $5^{th}$ layer from the top?

As we know a tree or a plant needs both soil and water along with sunlight to
grow. It will have the necessary nourishment in both water and sun to make its
leaves green and fruit to grow. A rural Indian school Gardner planted some
trees on his school at certain distances from the water body following a sequence.
There are 25 trees at equal distances of 5 meters in a line with a well, the
distance of the well from the nearest tree being 10 meters. A gardener waters
all the trees separately starting from the well and he returns to the well after
watering each tree to get water for the next.

(i) Distance travelled to water nearest tree and back to the well is:
(ii) Progression so formed in the above condition is
(iii) Distance travelled to water 25th tree.
OR
The total distance the gardener will cover in order to water all the trees.

Manpreet Kaur is the national record holder for women in the shot-put discipline. Her throw of 18.86 m at the Asian Grand Prix in 2017 is the biggest distance for an Indian female athlete. Keeping her as a role model, Sanjitha is determined to carn gold in Olympics one day. Initially her throw reached 7.56 m only. Being an athlete in school, she regularly practiced both in the mornings and in the evenings and was able to improve the distance by 9 cm every week. During the special camp for 15 days, she started with 40 throws and every day kept increasing the number of throws by 12 to achieve this remarkable progress.

Applications of Parabolas
Parabola has many applications in our day-to-day life. For example, if an object (projectile) is thrown in space, then the path of the projectile is a parabola. If we know the equation of the path of a projectile by using various properties of parabola, we can obtain may important results like greatest height attained by the projectile, its horizontal range reached etc.
Parabola: A parabola is the graph that results from $p(x) = ax^2 + bx + c$ they are symmetric about a vertical line known as the axis of symmetry and runs through the maximum or minimum point of the parabola which is called the vertex.

Graph of a quadratic polynomial is:
The number of zeroes that polynomial $p(x)=(x-2)^2+5$ can have is:
If a parabolic trajectory is represented by $x^2-4 x+3$, then its zeroes are:
Or
If one zero of a parabolic trajectory $p(y)=5 y^2-14 y+k$ is reciprocal of the other, the find the value of $k$ :
