Resolver en su blog las siguientes sucesiones y series Numéricas:



1.- a1= -27 d= 2 12 terminos

N=a1 + d =
- 27+2=-25+2=-23+2=-21+2=-19+2=-17+2=-15+2=-13+2=-11+2=-9+2=-7+2=-5+2=5-3+2=-1



2.- a1= -34/9 d= 2/3 9 terminos

n=a1+d=
34/9+2/3=120/27+2/3=414/81=1404/243=4711/729+2/3=15591/2187+2/3=51147/6561+2/3=166563/19683+2/3=539055/59049+2/3=1735263/177147


3.- a1= 67 d= -3.75 10 terminos

n=a1+d= 67+3.75=70.75+3.75=74.50+3.75=78.25+3.75=82+3.75=85.75+3.75=89.50+3.75=93.25+3.75=97+3.75=100.75+3.75=104.50


4.- a1= 128.15 d=-12.35 7 terminos

n=a1+d=

128.15+12.35=140.50+12.35=152.85+12.35=165.20+12.35=177.55+12.35=189.90+12.35=202.25+12.35=214.60+12.35=226.95


5.- a1= 63/7 d= -9/7 11 terminos

N=a1+d= 63/7+9/7=72/7+9/7=81/7+9/7=90/7+9/7=99/7+9/7=108/7+9/7=117/7+9/7=126/7+9/7=135/7=144/7+9/7=153/7+9/7=162/7

6.- a1= -3 an= 187 n= -75


sn = (a1+an) n = (-190)(-75) 14250= 7125


            2                      2           2



7.- a1= 2 an= 215 n= 164

sn = (a1+an) n = (217)(164) = 33588 =16794


            2                  2                   2




8.- a1= 21 an= 276 n= 321


sn = (a1+an) n = (297)(321) = 95337 = 47668.5


           2                  2                 2



9.- a1= -78 d= -49

N=a1+d (n-1)


=78+-49(n-1)

=-127(n-1)

N-1=-127

n=-127+1

n=-128

10.- a1= 345 d= -169

N=a1+d (n-1)


=345+ -169= (n-1)


=-514(n-1)

N - 1= -514

n= -514 + 1

n= -515
