Question

Find the middle term of the AP 0.6 1.7 2.8 3.9 27

Answer 1

Answer:

This is not understood to me.But I will try how many terms.

Answer 2

The middle term  a₁₃ ⇒13.8

Given:

AP 0.6 1.7 2.8 3.9 27

To find:

The middle term of AP

Step-by-step explanation:

0.6,1.7,2.8,3.9..27 is an Arithmetic Progression (AP) series

First-term a=0.6

Common difference d=1.7-0.6

                                  d=1.1

Let there be n terms in the given AP series.

Then, aₙ=27

          a+(n-1)d=27

Substituting the values in the above formula we get,

          0.6+1.1(n-1)=27

          1.1n+0.6-1.1=27

          1.1n=27+0.5

           n=27.5 / 1.1

           n=25

Here n is odd so,[(n+1)/2]th ⇒[(25+1) /2]th

13th term is the middle term

a₁₃=a+(13-1)d

   ⇒0.6+(12)1.1

   ⇒0.6+13.2

The middle term  a₁₃ ⇒13.8

Your question is incomplete but most probably your full question must be,
