Given that the difference between the 25th term and 12th term = - 52
Therefore
a + 24d - (a + 11d) = - 52
a + 24d - a - 11d = - 52
13d = - 52
d = - 4
Hence the common difference is - 4.
Therefore
a + 24d - (a + 11d) = - 52
a + 24d - a - 11d = - 52
13d = - 52
d = - 4
Hence the common difference is - 4.
