## Arithmetic Sequences

Assuming the sequence as Arithmetic Sequence and solving for d, the common difference, we get, 45 = 3 + (4-1)d 42= 3d 14 = d Hence, by adding 14 to the successive term, we can find the    ## How do you find the formula for an for the arithmetic sequence

The arithmetic sequence formula is given as, Formula 1: The arithmetic sequence formula is given as, an = a1 +(n−1)d a n = a 1 + ( n − 1) d. where, an a n = n th term, a1 a 1 = first term, and. d is the common difference. The above

## n-th Term of an Arithmetic Sequence

- the mean value of arithmetic series is x̅; - standard deviation of any arithmetic progression is σ. Then: a n = a 1 + d(n - 1) S = [n(a 1 +a n)]/2. x̅ = (a 1 +a n) /2. σ = |d|*√((n-1)*(n+1)/12) Example
