Solve U_{n}=100(1+0,2)^100-1

$$U _ { n } = 100 ( 1 + 0,2 ) ^ { 100 - 1 }$$

Solve for U_n

$$U_{n}=6901497876,8345458548673686329780708168010234321157869622016822008604576610843435253147523608071501615464448$$

Steps for Solving Linear Equation

Add 1 and 0,2 to get 1,2.

$$U_{n}=100\times 1,2^{100-1}$$

Subtract 1 from 100 to get 99.

$$U_{n}=100\times 1,2^{99}$$

Calculate 1,2 to the power of 99 and get 69014978,768345458548673686329780708168010234321157869622016822008604576610843435253147523608071501615464448.
