Question

16,_,_,31 fill this missing terms of the AP's​

Answer 1

Answer:

Step-by-step explanation:

Let the two terms be m1,m2

a=16 , l=31 , n=4 (number of terms)   ,d=m1-16

l=a+(n-1)*d

31=16+(4-1)*(m1-16 )

15=3(m1-16)

15/5=m1-16

5+16=m1

Therefore. m1=21  and d=m1-16=21-16=5

And m2=21+5=26
