3741 = p(p-1) over 2

The values of P are -87 or 86.

Step-by-step explanation:

Given:

Multiply by 2 on both the sides. This gives,

Now, use distribution property.

Now, add -7482 on both sides,

This is a quadratic equation of the form which can be solved using quadratic formula with

Therefore, the values of P are -87 or 86
