Positive Geometric Sequence Nth Term Calculator
Positive Geometric Sequence Nth Term. Term number: 1, 2, 3, 4, 5, 10, 15, 20 only. Example: First: 2 number, Ratio: 1.5 number, Term number: 10 count gives 76.88671875 number. Positive dimensionless terms and ratio; n selected from1,2,3,4,5,10,15,20; no alternating or infinite series claim. Only this original stated job is proposed, not full historical source coverage.

Positive dimensionless terms and ratio; n selected from1,2,3,4,5,10,15,20; no alternating or infinite series claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Repeated multiplication by one positive common ratio.
Accepted inputs: First: 0.001 to 10,000 number; Ratio: 0.1 to 2 number; Term number: choose 1 (1), 2 (2), 3 (3), 4 (4), 5 (5), 10 (10), 15 (15), 20 (20).
How the calculation works
a_n=a_1 r^(n-1)
Worked example
