Question

A. Find the sum 3+8+13+...+28

B. Find the first term and the common difference of the arithmetic sequence whose 7th term is 55 and 15th term is 37

C. An auditorium has 56 rows of seats. The first row contains 50
seats. As you move to the rear of the auditorium, each row has 7
more seats than the previous row.

How many seats are in row 21?

How many seats are in the auditorium?

D. Express the following sum in closed form.

∑k=1n (5+3⋅(k/n))^2

E.

Express the following sum in closed form.

∑k=1n (3+2k)^2

Answer #1

For an arithmetic sequence, a34=20. If the common difference is
-5, find:
First term:
Sum of first 66 terms:

The first difference of a sequence is the arithmetic sequence 1,
3, 5, 7, 9, .... Find the first six terms of the original sequence
in each of the following cases.
a. The first term of the original sequence is 2.
b. The sum of the first two terms in the original sequence is
9.
c. The fifth term in the original sequence is 32.

1)
Write nth term suggested by pattern.
1, 1/4, 1/16, 1/64, ...
2) Find first term (a1), the common difference (d), and give a
recursive formula (an) for sequence.
8th term is 55; 15th term is 118
3) Find the nth term and the indicated term of arithmetic
sequence whose initial term and common difference are given.
first term=6
common diff= -10
nth term?
13th term?
