Which of the following is the algebraic expression that best descibes the sequence 7, 14, 21, 28 ?

Respuesta :

'Multiples' of 7...? 

The algebraic expression that best describes the following sequence is +7 every time. Because, 7+7=14, 14+7=21, 21+7=28.

If you would like to get from term to term number, you multiply by seven every time. term 1x7=7, term 2x7=14, term 3x7=21.
