Step-by-step explanation:
Let the number of psychology books be 'x'.
and that of sociology books be 'y'.
x + y = 317 (given)
Number of sociology books sold was 89 less than that of psychology books.
y = x - 89
Which means,
x + x - 89 = 317
2x = 317 + 89
2x = 406
x = 406/2 = 203
y = 203 - 89 = 114
Hence, 203 psychology books and 114 sociology books were sold.

Assume the first integer is
.
then we have the sequence for the 6 numbers:
their sum equals 519. so we have the equation
now solve it.
now that we know the value of
, we can find the sequence of the integers:
