Sum of the first 8 terms in an arithmetic sequence is 304.
Given that, 
and 
.
<h3>What is sum of arithmetic sequence?</h3>
The sum of the arithmetic sequence formula is defined as the formula to calculate the total of all the terms present in an arithmetic sequence.
The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).
Now, sum of the first 8 terms in an arithmetic sequence is
(8/2).(2+74)
=4×76
=304
Therefore, sum of the first 8 terms in an arithmetic sequence is 304.

The general form of a function with a trigonometric sine is y=Asin(Bx+C)+D where A is the amplitude and B is the frequency. From f(x) = 3 sin (2x), A is equal to 3 which tells us that the graph has waves that has height from -3 to 3. B equals to 2 tells us that there are two waves between 0 and 2π.The period of the function then is <span>π. The graph goes through the (0,0) point.</span>
