Can someone tell me if this adjacent , vertical or linear

Aye i really don’t know this but i need more point so i am guessing it’s c. 2.0or you can use other apps to you get the answer

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
