a = -5
d = -5/2 - (-5) = 5/2
25th term = a + (n-1)d
= -5 + (24) 5/2
= -5 + 60
= 55
d = -5/2 - (-5) = 5/2
25th term = a + (n-1)d
= -5 + (24) 5/2
= -5 + 60
= 55

Given A.P -5, -5/2, 0, 5/2
Here first term(a) = - 5
common difference(d) = 5/2
25th term = a + 24d = - 5 + 24(5/2) = 55
Here first term(a) = - 5
common difference(d) = 5/2
25th term = a + 24d = - 5 + 24(5/2) = 55
