Suppose the sequence is defined by an = a0 + n*d
Then a1 = a0 + d = 15
and a13 = a0 + 13d = -57
Subtracting the first from the second: 12d = -72 so that d = -6
and then a0 - 6 = 15 gives a0 = 21
So a32 = 21 - 32*6 = -171

It is a + 8d where a is the first term and d is the common difference.
In an arithmetic sequence the same number (positive or negative) is added to each term to get to the next term.In a geometric sequence the same number (positive or negative) is multiplied into each term to get to the next term.A geometric sequence uses multiplicative and divisive formulas while an arithmetic uses additive and subtractive formulas.
It is -173
The 90th term of the arithmetic sequence is 461
T(n) = 5n + 16
It is an arithmetic sequence if you can establish that the difference between any term in the sequence and the one before it has a constant value.
In an arithmetic sequence, "a" typically represents the first term of the sequence. An arithmetic sequence is defined by a constant difference between consecutive terms, known as the common difference (d). The n-th term of the sequence can be expressed as ( a_n = a + (n-1)d ), where ( a_n ) is the n-th term, ( a ) is the first term, and ( n ) is the term number.

Arithmetic Sequence
An arithmetic sequence is defined as a sequence of numbers in which the difference between consecutive terms is constant. The number 35813 on its own does not represent an arithmetic sequence, as it is a single term. To determine if a sequence is arithmetic, you would need at least two terms to check for a constant difference.
Arithmetic- the number increases by 10 every term.
