OpenStudy (anonymous):

\[a_{p}=q\] \[a_{q}=p\] ??

If the pth term of an AP is q and the qth is p, the nth term is A) P2-q2 B) P+q-n C) P+q D) 0 E) 1 awright this is correct

OpenStudy (anonymous):

the answer is coming out to be B

OpenStudy (anonymous):

how dyu get that again?

OpenStudy (anonymous):

THE PTH term of an AP is : a+(p-1)d=q............(1) and the qth term of an AP is :: a+(q-1)d=p.............(2) now subtract (2) from (1), to get d=-1 now put the value of d in any one of the equations to get the value of a now,substitute the value of a and d in the nth term of AP ie a+(n-1)d

OpenStudy (anonymous):

a-first term of the sequence d-common difference

OpenStudy (anonymous):
