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.

Hello there!
a - 15 = 28k
a = 28k + 15
n = 30a + 3 = 30(28k + 15) + 3 = 840k + 453.
The only number that would fit between 1000 and 2000 is 1293.
In short, your answer is 1293.
Hope This Helps You!
Good Luck :)
Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
