Find recursive formulas for geometric sequences
By Khan Academy
Sal finds an explicit formula of a geometric sequence given the first few terms of the sequences. Then he explores equivalent forms the explicit formula and finds the corresponding recursive formula.
Manipulating formulas
By Khan Academy
Sal rewrites the formula for the area of a triangle so it is solved for height.
Find explicit formulas for arithmetic sequences
By Khan Academy
Sal finds explicit formulas of arithmetic sequences given the first few terms of those sequences. He also explores equivalent forms of such formulas.
Manipulating formulas
By Khan Academy
Sal rewrites the formula for the perimeter of a rectangle so it is solved for width.
