5th graders: 
x 96 = 16
4th graders: 
x 96 = 32
Remaining students: 96 - 16 - 32 = 48
2nd graders: 
x 48 = 12
Answer: 12 students
*********************************************************************************************
here is a breakdown by grade level:
5th graders = 16, 4th graders = 32, 2nd graders = 12, all other grades = 36
True because the 8 meters can be split up in 2 qnd
The word format would be forteen point zero five
It could also be said as Forteen and one half
We know that
<span>This is an arithmetic sequence with a1 = 21 and common difference, d = 2 [even integers]
</span><span>The general formula for the n-th term of an arithmetic sequence is
an = a1 + (n-1)d
</span><span>So
in this case we have
an = 21 + (n-1)2 ----> an = 2n + 19
</span>We need to find n for the last term, 45:
<span>45 = 2n + 19 -----> 2n = 26 -> n = 13
</span><span>The formula for the sum of the first n terms of a arithmetic sequence is
</span><span>S = (n/2)(a1 + an)
</span><span>S = (13/2)(21 + 45)-------> 429
the answer is
429</span>
