Step-by-step explanation:
Formula for mid-point is;
1.Given S(-3,4), U(-3,0) and T(5,0) then finding the mid-points
SU = [(-3+-3)/2,(4+0)/2] =(-3,2)
TU= [(-3+5)/2,(0+0)/2] =(1,0)
ST=[(-3+5)/2,(4+0)/2]=(1,2)
2.Mid-point formula for this case given W(-5,1) and Z(3,3) will be;
Midpoint = [ (x₁+x₂)/2,(y₁+y₂)/2]
Midpoint= [(-5+3)/2 ,(1+3)/2]
Midpoint=(1,2)
3. Finding the length of segments and the midpoint of the segments
Formula for length of segment, d, is given as;
For C(-1,5) and D(5,1)
Midpoint of the segment CD will be
[(-1+5)/2,(5+1)/2] = (2,3)
For E (-3,-6) and F(5,0)
The midpoint for segment EF will be;
[(-3+5)/2 ,(-6+0)/2] =(1,-3)
For L(-4,4) and M(-1,-5)

Answer:
lower limit is n=1
upper limit is n=18
n=1 to 18∑(7n-4)
Number of beads = 1125
Step-by-step explanation:
Given series is 3+10+17+24.....
we find the formula to find nth term(explicit formula)
first term (a1) = 3
common difference (d)= 7
total of 18 rows
So we find sum for n =1 to 18
lower limit is n=1
upper limit is n=18
n=1 to 18∑(7n-4)
(b) to find total number of beads we apply sum formula
n=18, a=3, d= 7
S= 9(125)=1125
Number of beads = 1125
