I assume that this is a sequence and you need to find the next number in the sequence.
The first two numbers are give as 133 and 142, we can get the difference between them by subtraction as follows:
142 - 133 = 9
This means that adding 9 will generate the next term as follows:
133
133+9 = 142
142 + 9 = 151
This means that : n=151
<span>When you round to the <em>nearest ten</em>, you are looking for numbers like 10, 20, 30, etc. These all have a zero in the ones place. In the case of 34 34 is closest to 30</span>
287,420
The difference is 
Explanation:
The expression is 
Removing the parenthesis, we have,
Factoring the terms 
and 
, we get,
Taking LCM, we get,
Simplifying the numerator, we get,
Subtracting the numerator, we have,
Hence, the difference is
62.5 is the answer to your question
I don’t know sorry I can’t help at least you found one
