a is 27
d is -4
rewrite the AP
-65,-61.......19,23,27
here,
first term is -65
d is 4
now apply formula,
a+(n-1) d
-65+(11-1)-4
a11 will be -25

d=-4
so, the new ap is
-65,-61,-57.........27
a=-65
d=-61-(-65) = -61+65 =4
a11=a+10d
=-65+10(4)
=-65+40 = -25
so, the new ap is
-65,-61,-57.........27
a=-65
d=-61-(-65) = -61+65 =4
a11=a+10d
=-65+10(4)
=-65+40 = -25
thanx, but they have asked 11 th term from the end....
but the answer is correct anyway.... tysm
ur wlcm
