Given first term (a), common ratio (r) and a integer n of the Geometric Progression series, the task is to print th n terms of the series.
Input : a = 2 r = 2, n = 4 Output : 2 4 8 16
We know the Geometric Progression series is like = 2, 4, 8, 16, 32 …….
In this series 2 is the stating term of the series .
Common ratio = 4 / 2 = 2 (ratio common in the series).
so we can write the series as :
t1 = a1
t2 = a1 * r(2-1)
t3 = a1 * r(3-1)
t4 = a1 * r(4-1)
tN = a1 * r(n-1)
To print the Geometric Progression series we use the simple formula .
TN = a1 * r(n-1)
