Answer:
not sure i hope you find someone to help u tho soon
Step-by-step explanation:
I think the way that you do is 5/5+3=5/8
5/8*4=2.5 so 2.5 is the answer
We can set up an equation.
.05 * 2^(n-1)
n being the nth term in the sequence
Plug in and solve.
.05 * 2^(20-1)
.05 * 2^19
.05 * 524, 288
The 20th term would be 262, 144.
