You could do this the long way and solve for the common difference but, in this particular case, there is a short cut because 7 - 4 = 3 = 3 - 1
As a result,
U7 - U4 = U4 - U1
so that U1 = 2*U4 - U7 = 2*141 - 132 = 150.
The 90th term of the arithmetic sequence is 461
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.
The difference between successive terms in an arithmetic sequence is a constant. Denote this by r. Suppose the first term is a. Then the nth term, of the sequence is given by t(n) = (a-r) + n*r or a + (n-1)*r

The 90th term of the arithmetic sequence is 461
To find the seventh term of a sequence, you need to identify the pattern or formula governing the sequence. If it's an arithmetic sequence, you can use the formula ( a_n = a_1 + (n-1)d ), where ( a_1 ) is the first term, ( d ) is the common difference, and ( n ) is the term number. For a geometric sequence, use ( a_n = a_1 \cdot r^{(n-1)} ), where ( r ) is the common ratio. Substitute ( n = 7 ) into the appropriate formula to find the seventh term.
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.
The nth term of an arithmetic sequence = a + [(n - 1) X d]
An arithmetic sequence
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.
One number, such as 7101316 does not define a sequence.
The one number, 491419 does not constitute a sequence!
A non-example of an arithmetic sequence is the series of numbers 2, 4, 8, 16, which is a geometric sequence. In this sequence, each term is multiplied by 2 to get to the next term, rather than adding a fixed number. Therefore, it does not have a constant difference between consecutive terms, which is a defining characteristic of an arithmetic sequence.
