Answer:
n+2
Step-by-step explanation:
This is a Typical Question on Arithmetic Progression with initial term as 2n+1
The next number in this particular series will be 2n+1+2 which is 2n+3 and so on. Thus a common difference of 2 exists.
The nth term of an Arithmetic Progression AP, bn is represented below where b1 is the first term
bn=b1 +(n-1)d where d is the common difference
For this particular series, the 4th term b4 is
b4= 2n+1+(4-1)2 0r b4 =2n+1+6=2n+7
sum of series is represented by equation: n(b1 +b4)/2 where b1 and b4 are 1st and 4th term respectively
Thus Sum required =4(2n+1+2n+7)/2=4(4n+8)/2=8n+16 0r n+2
1 foot = 12 inches
12 1/2 or 12.5 inches
18 and 3/4 or 18.75 X 12= 225
The ratio is 12.5:225 or to simplify 1:18.
It would have to be letter B because the exponents add up to the lines in the graph so in conculsion it is letter B.
Answer:
Coordinates of B are (-3,-2)
Step-by-step explanation:
AC in the horizontal direction is 14, so AB in the horizontal direction is 2/7 of 14 which is 4.
AC in the vertical direction is 7, so AB in the vertical direction is 2/7 of 7, which is 2.
To find the coordinates of B, you move right 4, and up 2 from A towards C.
Answer:
2(plus or minus) 1i
Step-by-step explanation:
First find the distance between the number that is being multiplied by the variable. Then, find the distance in absolute value between the numbers that have been added or subtracted.
3i - 2i = 1i
I 4 + -6 I
