Answer: 
Step-by-step explanation:
Given: Length of sandwich = 
Total people = 14
If everyone gets a same sized piece , then length of each piece should be


Hence, length of each piece = 
A6 = -8
a15= -62
There are (15 - 6) terms in between, therefore 9 terms in between.
-8 to -62 ... there is a difference of 54
54 ÷ 9 = 6
Therefore it gets -6 each term.
a6 = -8, a7= -14, a8 = -20 ......
