Web- the nth term of the sequence is a n; - the number of terms in the arithmetic progression is n; - the sum of the finite arithmetic progression is by convention marked with S; - 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 WebWe can find it by writing out the first few terms of the sequence and find their ratio. Another option is to realize that in summation notation, a sequence is written in the form k ∑ i = 1a(r)i, where r is the common ratio. Example 12.26 Find the sum: 15 ∑ i = 12(3)i. Try It 12.51 Find the sum: 15 ∑ i = 16(2)i. Try It 12.52
