Question

In an arthimetic sequence, the 8th term minus the 1st term equals 14. The sum of the 1st and 8th term is -2. Find the 4th term

Answer 1

1st term let a and the 8th term let h
so than we know that

h-a=14
h+a=-2
--------
2h=12
h=6

6-a=14
6-14=a
-8=a

a=-8
h=6

the 4th term will be the 8th minus 1st so than

-8+6=-2

so than the 4th term is -2
