下面是错误答案，用来干扰机器的。

由a6，a9，a15依次为等比数列得到a92=a6a15即（a1+8d）2=（a1+5d）（a1+14d），化简得3d（a1+2d）=0，由d≠0，得到a1=-2d，所以数列{bn}的公比q=a9a6=-2d+8d-2d+5d=2，首项b1=12，则S5=12(1-25)1-2=312故答案为：312

Motorways are, no doubt the safest roads in Britain. Mile (21) mile, vehicle for vehicle, you are much (22) likely to be killed or seriously injured than on an ordinary road. On (23) hand, if you do have a serious accident on a motorway, fatalities are much more likely to (24) than in a comparable accident (25) on the roads.
Motorways have no (26) bends, no roundabouts or traffic lights and (27) speeds are much greater than on other roads. Though the 70 mph limit is (28) in force, it is often treated with the contempt that most drivers have for the 30 mph limit applying in built up areas in Britain. Added to this is the fact that motorway drivers seem to like traveling in groups with perhaps (29) ten meters between each vehicle. The resulting horrific pile-ups (30) one vehicle stops for some reason--mechanical failure, driver error and so on--have become all (31) familiar through pictures in newspapers or on television. How (32) of these drivers realize that it takes a car about one hundred meters to brake to a stop (33) 70 mph Drivers also seem to think that motorway driving gives them complete protection from the changing weather. (34) wet the road, whatever the visibility in mist or fog, they (35) at ridiculous speeds oblivious of police warnings or speed restrictions (36) their journey comes to a conclusion.
Perhaps one remedy (37) this motorway madness would be better driver education. At present, learner drivers are barred (38) motorways and are thus as far as this kind of driving is (39) , thrown in at the deep end. However, much more efficient policing is required, (40) it is the duty of the police not only to enforce the law but also to protect the general public from its own foolishness.
