The simplest and most obvious sequence is given by the formula:
X[n]=136 - n*7
This gives X[11]=59.

115% = 1.15 = 1150/1000 = 23/20 = 13/20
a1 = 8 a9 = 48 so 8*d = 40 so that d = 5 And so a23 = 8 + 5*23 = 8 + 115 = 123
It can be almost any pattern. For example, Un = 120+n or Un = 115+2n or Un = 110+3n etc. Or, (1/25)*5^n or (1/78125)^5^2n etc.
