Question

For an ap if tn=24,n=12,d=2,a=?

Answer 1

Answer:

tn=24

a+ (n-1)d= 24

=>a+ 22=24

=>a=2

Answer 2

Answer:

We will get the value of a is 2.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

       Given data:-tn=24,n=12,d=2.

        To find:-Value of a=?

       Solution:-

• We know that Arithmetic Progression (AP) is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value, It is also called Arithmetic Sequence.
• The formula of A.P. is

         $a_{t}=a_{1}+(n-1) d$

        $a_{t}$ = the nᵗʰ term in the sequence.

        $a_{1}$ = the first term in the sequence.

        $d$ = the common difference between terms.

      Therefore,

          $a+(n-1)d=t_{n} \\=>a+(12-1)2=24\\=>a+(11)2=24\\=>a+22=24\\=>a=24-22\\=>a=2$
