Find a formula for an for the arithmetic sequence

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

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
