Answer:
_,13_,3.
a2=13.
a4=3.
an=a+(n-1)d.
a2=a+(2-1)d.
13=a+d......(1).
a4=a+(4-1)d.
3=a+3d......(2).
Substract (1) from (2).
a+3d=3.
a+d=13.
(-) (-) (-)
2d=-10.
d=-10/2.
d=-5.
Now substitute d=-5 in equation (1).
a+d=13.
a+(-5)=13.
a-5=13. (Because +×-=-).
a=13+5.
a=18.
a3=a+2d.
=18+2(-5).
=18-10.
=8.
The missing terms are 18 & 8 respectively.
I think this is your answer.
