a1 = 8
a9 = 48
so 8*d = 40 so that d = 5
And so
a23 = 8 + 5*23 = 8 + 115 = 123
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.
The nth term of an arithmetic sequence = a + [(n - 1) X d]
An arithmetic sequence
Arithmetic Sequence
Arithmetic- the number increases by 10 every term.
The 90th term of the arithmetic sequence is 461
T(n) = 5n + 16

Arithmetic Sequence
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!
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
It is a + 8d where a is the first term and d is the common difference.
