the formula is:
Sn= n [2(A1)+(n - 1)d]
2
for example the given sequence is when A1 = 4 and n = 10 when d = 2 here is the solution:
Sn = 4 [2(4)+(10 - 1)2]
2
Sn= 2 [6+(9)(2)
Sn = 2 [6+18]
Sn = 2 (24)
Sn = 48

What is the formula for the general term of the arithmetic sequence?
an = a1 + d(n - 1)
What is a infinite arithmetic sequence?
It is an arithmetic sequence for which the index goes on and on (and on).
What is the formula of finding the sum of a series of even numbers?
You didn't say the series (I prefer to use the word sequence) of even numbers are consecutive even numbers, or even more generally an arithmetic sequence. If we are not given any information about the sequence other than that each member happens to be even, there is no formula for that other than the fact that you can factor out the 2 from each member and add up the halves, then multiply by 2: 2a + 2b + 2c = 2(a + b + c). If the even numbers are an arithmetic sequence, you can use the formula for the sum of an arithmetic sequence. Similarly if they are a geometric sequence.
What is the type of sequence where the terms in the sequence are found by adding the same number each time?
That's an arithmetic sequence.
Is 13 17 21 25 29 a geomertic sequence or a arithmetic sequence?
Arithmetic
What is the formula for the following arithmetic sequence?
12, 6, 0, -6, ...
What is the formula for the general term of the arithmetic sequence?
an = a1 + d(n - 1)
What is the Th term of the arithmetic sequence given by the explicit rule?
The answer depends on what the explicit rule is!
What is the history of a arithmetic sequence?
origin of arithmetic sequence
What is a infinite arithmetic sequence?
It is an arithmetic sequence for which the index goes on and on (and on).
What is the difference between an arithmetic series and an arithmetic sequence?
An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.
What recursive formulas represents the same arithmetic sequence as the explicit formula an 5 n - 12?

Can a recursive formula produce an arithmetic or geometric sequence?
arithmetic sequence * * * * * A recursive formula can produce arithmetic, geometric or other sequences. For example, for n = 1, 2, 3, ...: u0 = 2, un = un-1 + 5 is an arithmetic sequence. u0 = 2, un = un-1 * 5 is a geometric sequence. u0 = 0, un = un-1 + n is the sequence of triangular numbers. u0 = 0, un = un-1 + n(n+1)/2 is the sequence of perfect squares. u0 = 1, u1 = 1, un+1 = un-1 + un is the Fibonacci sequence.
