Question

in the following AP find the missing term
5,_,_,9.5​

Answer 1

Answer:

6.5 & 8

Step-by-step explanation:

A¹=5,A⁴=9.5

A1=A=5

A4=A+(N-1)D=9.5. EQ(1)

Put the value of A=5 in EQ(1)

Therefore

5+(4-1)D=9.5

5+3D=9.5

3D=9.5--5

D=4.5/3=45/3*10

D=15/10=1.5

Now find the Missing values

A2=A+D=5+1.5=6.5

A3=A2+D=6.5+1.5=8

Final A.P.

5,6.5,8,9.5
