Hope you realize that the bot is wrong again
Your question should have asked for a "common ratio"
common difference refers to an arithmetic sequence
to have a GS, ...
t+4,t+10,t+20
(t+10)/(t+4) = (t+20)/(t+10)
t^2 + 24t + 80 = t^2 + 20t + 100
4t = 20
t = 5
the terms are : 9, 15, 25 , ..... and the common ratio is 5/3
