Progresion aritmetica 02 SECUNDARIA (3ºESO)

If this video helped you and you want to see Unicoos continue to grow, SUBSCRIBE, click "Like," and SHARE. If you also join us at http://www.unicoos.com, it'll be great! #seeyouinclass We'll do an exercise on arithmetic progressions (sequences) (those in which you always have to add or subtract the same number to find the next term). I'm asked to find three terms of an arithmetic progression knowing the value of their sum and the sum of their squares. We'll set up the corresponding equations and solve the resulting NONLINEAR SYSTEM OF EQUATIONS to find the value of the first term (a1) and the difference (d). I recommend you visit other sequence videos in this section of the website... http://www.unicoos.com/asignaturas/ma...
