You would solve this using geometric mean.
x/5=26/x
x^2=130
x= the square root of 130 or it is about 11.40175......
96 divided by 3 = 32 so
32-1=31 and 32+1=33 so tou get 31,32,33
Answer: no solution
it won’t work no matter what you are trying to figure out.
a(1) = 3(1)-1 = 3-1 = 2
a(2) = 3(2)-1 = 6-1 = 5
a(3) = 3(3)-1 = 9-1 = 8
So, the sequence would be 2,5,8,11....
