Answer:
Step-by-step explanation:
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.

6 is in the thousands place, since 3 is less than five, you round down.
Round up 15.23 to the nearest tenth.
15.23
Look after the tenth place which is 3. Is this number number before or after 5? Yes! Its before, so we round back which would make 15.23 to the nearest tenth is 15.20.
15.23 rounded to the nearest tenth = 15.20.
<h3>Answer:</h3>
<h3>Explanation:</h3>
The 
th term of an arithmetic sequence is explicitly defined as 
where 
is the first term of the sequence and 
is the the common difference.
From the given first five terms of the sequence we can see that the first term is 
so 
.
The common difference, , can be calculated by 
so we'll find the common difference of the given sequence by letting 
.
Now let's plug everything we know.
