Question

Find the 6th term from the end of the a.p 5,2,-1,-4,......…….-31

Answer 1

Answer:

Given: The arithmetic progression 5, 2, -1,

-4, -31

To find: The 6th term of the Arithmetic Progression.

Solution:

Now we have given the arithmetic progression 5, 2, -1, -4, -31.

The first term a is 5.

The common difference is 2 - 5 = -4

. (-1) = -3.

The last term is -31.

Now the sixth term of the Arithmetic Progression will be:

a + 5d

So putting the values in the sixth

term, we get:

5 + 5(-3)

5 - 15

-10

... 45%

So the sixth term of the arithmetic progression 5, 2, -1, -4,...........-31 is -10.

Answer 2

Answer:

a1=5

d=a2-a1=2-5=-3

so, 6n=a+5d

=>a6=5+5(-3)

=5-15

=-10

therefore 6th term is -10
