Step-by-step explanation:
you can use division method
Answer:
Sequence One
Step-by-step explanation:
S = a₁ / (1 − r) is the infinite sum of a geometric series where |r| < 1.
Sequence One: r = 1/5
Sequence Two: r = 2
Sequence Three: not geometric
Sequence Four: r = -3/2
Only Sequence One has |r| < 1.
Number of unburnt cells, x= 151.9 x 10^10
<u>Step-by-step explanation</u>:
Number of unburnt cells= x
x = ?
<u>Given</u>: 2% cells are burnt
(3.1 x 10^10 cells)/2% = x/98%
x = (3.1 x 10^10)(98%/2%)
=(31000000000)(49)
x =151.9 x 10^10
