So i'm doing geometry sequencing and the sequence is -4, 0, 6, 14, 24, 36 and i need to find the nth term basically the formula on how to solve the whole thing but my teacher is horrible at instructions and i'm left clueless on how to do this

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297

Can some one explain how to slove specifically, what is the value of x? 0.9(x+1.4)-2.3+0.1x=1.6 enter the answer as a decimal in the box. x= ?
