8/10 = ?/45
8/10 = 36/45
1.) 4, 2, 1, 1/2,1/4,... 2.) 2, 6, 18, 54, 162, … 3.) <span>−4, −16, −64, −256, … are geometric sequences because common ratio is same. Example: 1.) ratio of 1st and 2nd term is 1/2. similarly ratio of 3rd and 4th term is 1/2 and so on. </span>
The sequence is ×2.
12,288 is the 12th term.
24,570 is the answer. It is the sum.
50 is the value cause 20 is 40 of the percent, 20+20 is 40 now you made it into 80%.20% is remaining so add 10.
