Question

The sum of p and q(algebra)​

Answer 1

Sum of p and q is equals to p×q = pq

Vaise I don't know algebra... Xd

Answer 2

Step-by-step explanation:

HINT:

Sn=n2(2a+(n−1)d)

Where a is the first term, d, the common difference, and n he no. of terms

So,

Sp=p2(2a+(p−1)d)=q

Sq=q2(2a+(q−1)d)=p

Subtracting the two :

q−p=ap+p2d2−pd2−aq−q2d2+qd2=a(p−q)+d(p−q)(p+q)2−d(p−q)2

Divide by (p−q) to get to:

12(2a+((p+q)−1)d)=−1
