the first 5 terms of geometric progression if a equals to 1024 and r equals to 1 by 2 is:-
1024, 512, 256, 128, 64
When a = 1024
r = 1/2
By applying the formula
Tn = ar^n-1
We will get
T1 = a = 1024
T2 = ar^2-1 = ar = 1024 * (1/2) = 512
T3 = ar^3-1 = ar^2 = 1024 * (1/2) * (1/2) = 256
T4 = ar^4-1 = ar^3 = 1024 * (1/2) * (1/2) * (1/2) = 128
T5 = ar^5-1 = ar^4 = 1024 * (1/2) * (1/2) * (1/2) * (1/2) = 64
The GP will be 1024, 512, 256, 128, 64
