Explanation Theorem used: If | r | < 1 , then the geometric series ∑ n = 0 ∞ a r n = a + a r + a r 2 + ⋯ converges and it sum is a 1 − r ; that is, ∑ n = 0 ∞ a r n = a + a r + a r 2 + ⋯ = a 1 − r . The series diverges if | r | ≥ 1 . Calculation: The given geometric series is ∑ n = 1 ∞ ( − 1 ) n − 1 ( 1 2 ) n . Simplify the series ∑ n = 1 ∞ ( − 1 ) n − 1 ( 1 2 ) n as follows. ∑ n = 1 ∞ ( − 1 ) n − 1 ( 1 2 ) n = ∑ n = 1 ∞ ( − 1 ) n ( − 1 ) − 1 ( 1 2 ) n = ∑ n = 1 ∞ 1 − 1 ⋅ ( − 1 2 ) n = ∑ n = 1 ∞ ( − 1 ) ( − 1 2 ) n The series ∑ n = 1 ∞ ( − 1 ) ( − 1 2 ) n is a geometric series with a = − 1 and r = | − 1 2 | = 0
