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.
