The explicit formula would be
This is a geometric sequence, since each term is found by multiplying the previous term by a constant. The explicit form of a geometric sequence is given by
where r is the common ratio, or constant we multiply by, and g₁ is the first term. For our sequence, g₁ = 5 and r = 3, so our formula is
Answer:
lol
Step-by-step explanation:
What is the equation for three times a number is 27?
3 times a number (9) equals 27. 3 times 9 equals 27. This is correct and we have found and checked our answer!
Answer:
162°
Step-by-step explanation:
Total angle:
(5 - 2)×180
540
2x + 3x + 4x + 5x + 6x= 540
20x = 540
x = 27
Largest interior angle: 6x
6(27)
162
To use mental math think instead of 81 to 80 and 16 to 10 and subtract that and add the other numbers and subtract that and you will have your answer presto!
There are 25 identical squares arranged inside the 5 by 5 square matrix. From the drawing it's evident that the length of the side of any one of the smaller squares is just 1. Thus, the perimeter of this one smaller square is P = 4(1), or 4.
The desired perimeter is 4.
