progresion aritmetica
an = a1 + (n -1) r an = ultimo termino a1 = primer termino r = razon n numero de termino an = 12 a1 = -3 n=7 r =?
r = (an -a1)/(n-1)
r = ( 12-(-3))/(7-1)
r = (12+3)/ 6
r = 15/6
r = 5/2
termino 1 = -3
termino 2 = -3 +5/2= ( -6 +5)/2 = -1/2
tercer termino = -1/2 +5/2 = (-1 +5)/2 = 4/2 = 2
cuarto termino = 2 +5/2 = (4 +5)/2 = 9/2
quinto termino =9/2 +5/2 = (9+5)/2 = 14/2 =7
sexto termino = 7 +5/2 = ( 14 +5)/2 = 19/2
septimo termino = 19/2 +5/2 = (19+5)/2 = 24/2 =12
