The forces F1, F2, . . . , Fn acting at the same point P are said to be in equilibrium if the resultant force is zero, that is, if F1 F2 ... Fn 0. Find

(a) the resultant forces acting at P, and
(b) the additional force required (if any) for the forces to be in equilibrium.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
