Answer:
Hence Proved, rth term of the AP is p+q-r
Step-by-step explanation:
If the pth term of an AP is q and the qth term is p
Let first term of AP is a and common difference is d
Solve for a and d
Put d=-1 into
We need to find rth term of same AP where a=p+q-1 and d=-1
Hence proved, rth term of the AP is p+q-r
