Answer:
36
Step-by-step explanation:
Sean purchased a printer and laptop
He sold both for 1,500
He sold the laptop at 1,350
Therefore the cost of the printer can be calculated as follows
1500-1350
= 150
24/100×150
= 0.24×150
= 36
Henve the cost of the printer is £36
86.88 kilometers is 53.98 miles
The only formula that can be used to describe the sequence is definitely the third one

. So count like that

and so on. You can check others by yourself to check if I'm right or not.
