Answer:
105th term of given series is

Step-by-step explanation:
Given series is

As we can see,

Also,

hence, we can say given series is in arithmetic progression,
with common difference,

As given in question the nth term in A.P is given by

since we have to find the 105th term, so we can write



Hence, the 105th term of given series of A.P is
.

b. Stem and leaf plot
Step-by-step explanation:
A stem-and-leaf plot shows the data shape and the densities of the different classes in a graphical form such that the information in the data such as the data characteristics are self displayed by the data numbers arranged in the stem-and-leaf plot. The stem-and-leaf plot keeps the raw numerical data, in the form they were obtained and by their arrangement, outliers are easily spotted.
We need to expand the square binomial and then multiply:
<span>3x(x + 3)^2
= 3x(x + 3)</span>(x + 3<span>)
= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x</span>
