S_3=35

Step-by-step explanation:

Given: $S_1=3\,,S_n=7(S_{n-1}-2)$

To find: S_3

Solution:

First find S_2

Put n=2 in $S_n=7(S_{n-1}-2)$

$S_2=7(S_{2-1}-2)\\S_2=7(S_1-2)$

Put S_1=3

S_2=7(3-2)=7

Now find S_3

Put n=3 in $S_n=7(S_{n-1}-2)$

$S_3=7(S_{3-1}-2)\\S_3=7(S_{2}-2)$

Put S_2=7

S_3=7[(7)-2]=7(5)=35
