Answer:
The equation for the nth term of the given arithmetic sequence is:
Step-by-step explanation:
We need to write an equation for the nth term of the arithmetic sequence:
15,28,41 ....
The equation for arithmetic sequence is:
Where is the nth term, is first term and d is common difference
In the given sequence we have:
a₁ = 15
a₂ = 28
We can find common difference using the formula:
So, the common difference d is 13
Now, equation for nth term will be:
So, the equation for the nth term of the given arithmetic sequence is:
where n=1,2,3..

Answer:
3.14 km
Step-by-step explanation:
we know that area of a circle is πr², where r is the radius
if here radius is 1 kilometres, π is 3.14
then, circle's area = 3.14 * 1 * 1 = 3.14 km
1) with 3/5 as a fraction one whole number can be written as 5/5
so you could rewrite 4 as 3 and 5/5 now subtract 3/5 and you are left with
3 and 2/5
2) one whole number can be written as 7/7
Now you have 4 and 7/7 minus 4/7 to get 4 and 3/7
Using the same steps for the rest:
3) 5 and 3/3 -2/3 = 5 and 1/3
4) 4 and 8/8 - 7/8 = 4 and 1/8
5) 6 and 5/5 - 2/5 = 6 and 3/5
