The first term of an arithmetic sequence is 1.2 with a common difference of 8.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have:
Tenth term of an arithmetic sequence = 73.2 or
a+(10-1)d = 73.2 ....(1)
Second term of an arithmetic sequence = 9.2 or
a+(2-1)d = 9.2 .....(2)
Where a is the first term and d is a common difference.
Solving equations (1) and (2)
From the equation (2) put the value of d in the equation (1), we get:
a+9(9.2-a) = 73.2
a+82.8 - 9a = 73.2
-8a = -9.6
a = 1.2
Thus, the first term of an arithmetic sequence is 1.2 with a common difference 8.

I'm not good with math, sorry
Answer:
I drew it in the photo.
Step-by-step explanation:
In order to show a model of 2/6 divided by 1/12, we can draw 2 rectangles. In 1 rectangle, it would be divided into 6 sections with 2 shaded sections. In the other rectangle, it would be divided into 12 sections with 1 section shaded. We can show the division in a question: How many 1/12's fit into 2/6? 4 1/12's fit into 2/6.
