Answer:
x=3
Step-by-step explanation:
1/4(12x + 4) - 14= -1/2(8x - 16)
1. Simplify each side my multiplying
3x - 13 = -4x + 8
2. Add 13 on each side
3x = -4x + 21
3. Add 4x on each side
7x = 21
x=3

Answer:
4^n-1
Step-by-step explanation:
So given sequence is a geometric sequence where terms increase or decrease by a constant common ratio(r)
Formula to find terms in Geometric sequence is " ar^n-1 where a is first term , r is common ratio and n is number of items
In this case , first term (a) is 1 , common ratio(r) is succeeding term/preceding term = 4/1 = 4 and number of items be (n).
Applying "ar^n-1 " we get,
1*4^n-1 which is , 4^n-1
Thats the formula which represents the situation....
