Answer: 
Step-by-step explanation:
Since we have given that

Now, we know the rule for summation , we'll apply this ,

Now, it becomes geometric progression, so we us the formula for sum of terms in g.p. which is given by

So, our equation becomes ,

Hence ,

i) u + 3 V
1 by 2 + 3 *minus 2
1 by 2 -6
1 - 12 by 2
- 11 by 2
ii) - 3 * 1 by 2 + 2 * -2 + 3 by 4
minus 19 by 4
Answer: x = 7
Step-by-step explanation:
2x - 6 = 8x - 48
+48
2x + 42 = 8x
-2x
42 = 6x
/6
7 = x
