Question

multiple choice questions the missing terms I ap_13,_3 are​

Answer 1

Answer:

18, 13, 8, 3...............

Answer 2

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.
