Answer: the correct option is option 1
Step-by-step explanation:
The first 3 terms of the sequence are
1, 2, 4, ..
The rate at which each term is increasing is in geometric progression.
The expression for the nth term of geometric sequence is
Tn = ar^n-1
Tn = the nth term of the sequence
a = the first term of the sequence
r = common ratio
From the information given,
The common ratio is expressed as the ratio of a term to its previous consecutive term. It becomes
2/1 = 4/2 = 2. Therefore
r = 2
a = 1
We want to determine the 7th term. It becomes
T7 = 1×2^7-1
T7 = 2^6 = 64
The 7th term is 64
Answer:
Because it cannot be written as a fraction
Step-by-step explanation:
The square root of any non-perfect square will always be irrational and cannot be written as a fraction. The sqrt(21) has no repeating digits because its digits go on forever.
6300kg = 6300000g 6300000g =6.3 x 10^6 g
Answer:
x = - 6
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis with equation
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, - 7 ) with x- coordinate - 6 , then
x = - 6 ← equation of line
