Answer:
You didn't give the geometric sequence in question.
But to find the nth term of a geometric sequence, use the formula
Sn = ar^(n - 1)
Where a is the first term of the sequence
r is the common ratio of the sequence.
Example: To find the nth term of the geometric sequence
1/2, 1/4, 1/8, 1/16, ...
Here, a = 1/2
r = 1/4 ÷ 1/2 = 1/8 ÷ 1/4 = 1/16 ÷ 1/8 = 1/2.
Sn = (1/2)(1/2)^( n - 1)
Apply this method to the sequence you were given, it will be helpful.
3 x 2 and 1/3? The answer is 7.
Answer:
The value of x is 49 and the value of AB is 90
Step-by-step explanation:
You know that AB and DE are congruent. That information is given to you.
You set the equations equal to each other and then solve.
2x - 8 = x + 38
Subtract x
x - 8 = 38
Add 8.
x = 49
Plug back into 2x - 8 to find the value of AB
2 times 49 - 8
98 - 8
90
The answer would be a=u divided by b-k
" The opposite of " could be the answer
