Ejercicios Guia Prueba 1 a) $a^1=185000$ / b) $a^2=188000$ / c) $a^3=191000$ $d_1=188000-(185000)=3000$ $d_2=191000-(188000)=3000$ $d=3000$ b)

$\sum _{i=1}^n=\frac{n}{2}[2\ast 18500+(n-1)\ast 3000]$

e) $\sum _{i=25}^{36}{a}_i=\sum _{i=1}^{36}{a}_i-\sum _{i=1}^{24}{a}_i$

f) $\sum _{i=37}^{48}{a}_i=\sum _{i=1}^{48}{a}_i-\sum _{i=1}^{36}{a}_i$
