HERE'S YOUR ANSWER FRIEND,
GIVEN A.P. = 6,5.5,......-12.
LET THE FIRST TERM OF AP BE a AND THE COMMON DIFFERENCE BE d.
HERE, a = 6
and d = 5.5 - 6
= -0.5
WE KNOW,
an = a + (n - 1)d
==> -12 = 6 + (n - 1)(-0.5)
==> -18 = (n - 1)(-0.5)
==> 36 = (n - 1)
==> n = 37
HENCE, THERE ARE 37 TERMS IN THE GIVEN AP.
HOPE IT HELPS YOU.
