Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.150 Geometric Series Sum Formula for Finite and Infinite Series skill assessments:

Problem 1Difficulty: Mastery

Let S be the sum of the infinite series 12 + 3 + 0.75 + 0.1875 +.... What is 4S?

A48

B56

C60

D64

Solution & Explanation:The ratio is 3 divided by 12 = 0.25, so r = 0.25 and a = 12. Sum S = 12 divided by (1 - 0.25) = 12 divided by 0.75 = 16. Then 4S = 64.

Problem 2Difficulty: Mastery

The infinite series 5 - 5r + 5r squared - 5r cubed +... converges and has sum 4. Find r.

A0.2

B0.4

C0.25

D0.8

Solution & Explanation:This is geometric with first term a = 5 and common ratio equal to -r. Sum S = 5 divided by (1 - (-r)) = 5 divided by (1 + r). Set 5 divided by (1 + r) = 4, so 1 + r = 1.25 and r = 0.25. Also |-r| < 1 holds.

Problem 3Difficulty: Mastery

For the series 3 + 1.5 + 0.75 +..., find the smallest n so that the partial sum S_n is within 0.01 of the infinite sum.

Solution & Explanation:This is geometric with a = 3 and r = 0.5, so the infinite sum is S = 3 divided by (1 - 0.5) = 6. The error after n terms is S - S_n = 6(0.5 raised to n). Set 6(0.5 raised to n) < 0.01. Since 0.5 raised to 9 is 0.001953125 (error ≈ 0.0117) and 0.5 raised to 10 is 0.0009765625 (error ≈ 0.00586), the smallest n is 10.
