Sequence 2, - 4, 8, -16, 32 ....
First term = a = 2
Problem
Find the nth term
tn = (-1 )^(n -1) * (a)^n answer or
tn = (-1)^(n - 1) * 2^n
where a is defined as the first term (it usually is given that designation).
Try a few to make sure the formula is correct
<em>n = 1</em>
t1 = (-1)^(1 - 1) * 2^1
t1 = (-1)^0 * 2
t1 = 1 * 2 = 2
<em>n =2</em>
t2 = (-1)^(2 - 1) * 2^2 = (-1)^1 * 4 = -4
Let the what be x
56%* x=14
x= 14/56%
x= 25%
I think it is C
Hope this helped

Answer:
The value of m is 44
Step-by-step explanation:
We have given:
1/2 m - 3/4 n = 16
Put the value of n in the given equation
1/2m - 3/4(8)=16
Now 4 and 8 will be canceled out by the table of 4
1/2 m - 3(2)=16
1/2m - 6 = 16
Now take the L.C.M of the denominator and solve for numerator:
m-2(6)/2 = 16
m-12/2 = 16
m-12 = 16*2
m-12 = 32
Add 12 at both sides:
m-12+12 = 32+12
m= 32+12
m=44
The value of m is 44....
