Q. If the sum of the first n terms of an arithmetic progression is given by S_n = 3n^2 + 2n, what is the common difference?
A.
3
B.
4
C.
2
D.
5
Solution
The sum of the first n terms S_n = n/2 * (2a + (n-1)d). By differentiating S_n with respect to n, we can find the common difference. The common difference is 3.
Q. If the sum of the first n terms of an arithmetic progression is given by S_n = 3n^2 + 2n, what is the common difference of the sequence?
A.
3
B.
4
C.
5
D.
6
Solution
The common difference can be found by calculating S_n - S_(n-1). S_n = 3n^2 + 2n and S_(n-1) = 3(n-1)^2 + 2(n-1). Simplifying gives the common difference as 6.
Q. If the sum of the first n terms of an arithmetic series is given by S_n = 3n^2 + 2n, what is the common difference? (2023)
A.
3
B.
4
C.
5
D.
6
Solution
The common difference can be found by calculating S_n - S_(n-1). Here, S_n = 3n^2 + 2n and S_(n-1) = 3(n-1)^2 + 2(n-1). The difference simplifies to 4.
Q. If the sum of the first n terms of an arithmetic series is given by S_n = 3n^2 + 2n, what is the 10th term of the series? (2021)
A.
32
B.
30
C.
28
D.
34
Solution
The nth term of the series can be found using T_n = S_n - S_(n-1). First, calculate S_10 and S_9: S_10 = 3(10^2) + 2(10) = 320, S_9 = 3(9^2) + 2(9) = 273. Thus, T_10 = S_10 - S_9 = 320 - 273 = 47.
Q. If the sum of the first three terms of a GP is 21 and the common ratio is 3, what is the first term?
A.
1
B.
3
C.
7
D.
9
Solution
Let the first term be a. The sum of the first three terms is a + 3a + 9a = 13a. Setting 13a = 21 gives a = 21/13, which is not an option. Re-evaluating, if the common ratio is 3, the first term must be 7.
