4.- a1= 128.15 d=-12.35 7 terminos
OPERACION:
a1+d = 128.15+ (12.35) = 115.8 +(-12.35) = 103.45….etc
R= 115.8 103.45 91.1 78.75 66.4 54.05 41.7
5.- a1= 63/7 d= -9/7 11 terminos
OPERACION:
a1+d = 63/7+ (9/7) = 54/7 +(9/7) = 45/7 …etc
R= 54/7 45/7 36/7 27/7 18/7 9/7 0/7 -9/7 -18/7 -27/7 -36/7 -45/7
6.- a1= -3 an= 187 n= -75
OPERACION:
(a1+ an)n/2 = (-3+187)-75/2
(-3+187)-75/2 = (184)-75/2 = 13800/2= 6900
R= 6900.
7.- a1= 2 an= 215 n= 164
OPERACION:
(a1+an)n/2 = (2+215) 164/2
(2+215) 164/2= (217) 164/2= 35588/2 = 17794
R= 17794.
8.- a1= 21 an= 276 n= 321
OPERACION:
(a1+an)n/2 =(21+276)321/2
(21+276)321/2 = (297) 321/2 = 95337/2 = 47668.5
R= 47668.5
9.- a1= -78 d= -49
OPERACION:
a1+d (n-1) =-78+-49 (n-1)
-78+-49(n-1) =-127(n-1)
(n-1) = -127
n= -127+1
n= -128
10.- a1= 345 d= -169
OPERACION:
a1+d(n-1) = 345+-169 (n-1)
345+-619 (n-1) = 176 (n-1)
(n-1) = -176
n= -176+1
n= -177
