Question

IF an AP IF a=4 n=7 and anan=4 then the value of d is​

Answer 1

Answer:

In an AP if a = 4 that means frist term of the AP is 4.

n = 7 i.e there are 7 terms in the AP.

an = 4 i.e nth term of the A.P is 4

We know that an = a + (n-1)d

So 4 = 4 - (7- 1) d

➡️ 4 - 4 = 6d

➡️ 0 = 6d

➡️ d = 0
