Question Solve the equation Solve for a Solve for d Solve for n Load more a=dn2−dns Evaluate s=2n(2a(n−1)d)Remove the parentheses s=2n×2a(n−1)dMultiply the terms More Steps Multiply the terms 2n×2Cancel out the common factor 2 n×1Multiply the terms n s=nad(n−1)Rewrite the expression s=(dn2−dn)aSwap the sides of the equation (dn2−dn)a=sDivide both sides dn2−dn(dn2−dn)a=dn2−dnsSolution a=dn2−dns Show Solution
