the series is 1,20,x,266,675
taking the adjacent we have
20-1,x-20,266-x,675-266
so we will get
19,x-20,266-x,409
again,
x-20-19,266-x-x+20,409-266+x
we will get
x-39,286-2x,143+x
again
286-2x-x+39,143+x-286+2x
we will get
325-3x,3x-143
again,
3x-143-325+3x
we will get
6x- 468
then equate it to 0
that is
6x-468=0
6x=468
x=468/6
x=78
so,
the series is
1,20,78,266,675
