The mean
The 90th term of the arithmetic sequence is 461
an arithmetic series equation is a*r^(n-1) where a is the starting value, r is the number you are continuously adding, and n is the term you are looking to find
The series appears to be an arithmetic series in which the n'th term is 1.5 + (n - 1)2.5. If so, the next two terms are 11.5 and 14.
This appears to be a declining arithmetic series. If it is, the next term is 5, because each term is 3 less than the preceding term.=================================The 'N'th term is: [ 23 - 3N ].
The mean
Nth number in an arithmetic series equals 'a + nd', where 'a' is the first number, 'n' signifies the Nth number and d is the amount by which each term in the series is incremented. For the 5th term it would be a + 5d
In an arithmetic series, each term is defined by a fixed value added to the previous term. This fixed value (common difference) may be positive or negative.In a geometric series, each term is defined as a fixed multiple of the previous term. This fixed value (common ratio) may be positive or negative.The common difference or common ratio can, technically, be zero but they result in pointless series.
A series is a sequence of numbers that follows an identifiable pattern. There are two basic forms of series: Arithmetic, where the difference between successive terms is the same number. 1, 4, 7, 10, 13, 16, 19, 21 is an arithmetic series, each successive term is 3 larger than the previous term Geometric, were successive terms are achieved by multiplying each term by the same number 1, 2, 4, 8, 16, 32, 64, 128 is a geometric series, each successive term is the result of multiplying the previous term by 2
The 90th term of the arithmetic sequence is 461
In an arithmetic progression (AP), each term is obtained by adding a constant value to the previous term. In a geometric progression (GP), each term is obtained by multiplying the previous term by a constant value. An AP will have a common difference between consecutive terms, while a GP will have a common ratio between consecutive terms.

The nth term of an arithmetic sequence = a + [(n - 1) X d]
-5 19 43 67 ...This is an arithmetic sequence because each term differs from the preceding term by a common difference, 24.In order to find the sum of the first 25 terms of the series constructed from the given arithmetic sequence, we need to use the formulaSn = [2t1 + (n - 1)d] (substitute -5 for t1, 25 for n, and 24 for d)S25 = [2(-5) + (25 - 1)24]S25 = -10 + 242S25 = 566Thus, the sum of the first 25 terms of an arithmetic series is 566.
It is a + 8d where a is the first term and d is the common difference.
