Someone please explain step by step. Find the 10th term of the geometric sequence whose common ratio is 1/2
and whose first term is 5.

Step-by-step explanation:

geometric progression formula:

given:

common ratio, r = 1/2

1) find the value of a

we're finding the 1st term, so substitute 1 into n:

first term is 5. so we substitute 5 into the equation:

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
