Question

The 7th term of an A.P. is 24 and 13th term is 52 find the A.P.​

Answer 1

Answer:

a₇ => 24

a₇ => a + (7 - 1) d = 24

a₇ => a + 6d = 24    ..(i)

a₁₃ => 52

a₁₃ => a + (13 - 1) d = 52

a₁₃ => a + 12d = 52     ..(ii)

Solving Equation (i) and (ii), we get,      (Substracting)

a +12d = 52

a + 6d = 24

-   -          -    

      6d = -28

       6d = 28

         d = 4.66

Hence, d = 4.66 it cannot form an AP.
