An arithmetic sequence has the terms a6=53 a 6 = 53 and a8=61 a 8 = 61 . questions: what is the value of d d ? answerincorrect what is the value

The given terms are two terms apart, so their difference is twice the difference of adjacent terms.

The value of d is 4.

The value of d is 4.

Step-by-step explanation:

It is given that the 6th term of an AP is and 8th term is .

The nth term of an AP is

6th term of an AP is .

             .... (1)

8th term is .

           .... (2)

Subtract equation (1) from equation (2).

Divide both sides by 2.

Therefore the value of d is 4.
