Answer:

  • The value of a is 5/3.

Given:

  • 3a +24, 49, 29 and 6a + 31 are sequential members of an arithmetic progression.

To find:

  • The value of a.

Solution:

Here,

\sf{t_{1}} = 3a + 24,

\sf{t_{2}} = 29,

\sf{t_{3}} = 49,

\sf{t_{4}} = 6a + 31

If they are in arithmetic progression, then

\sf{t_{2}-t_{1}=t_{3}-t_{2}}

\sf{\therefore} 49 - (3a + 24) = 29 - 49

\sf{\therefore}25 - 3a = 20

\sf{\therefore} -3a = -5

\sf{\therefore} a =5/3

The value of a is 5/3.
