Hello :
the general term is : an = a1×r^(n-1)
a1 : the first term....( a1 = 6)
r : the common ratio......( r = -1/3 )
when : n = 8 a8 is the eighth term : a8 = 6×(-1/3)^7
a8 =- 6×(1/3)^7 because : (-1/3)^7 = - (1/3)^7
a8 = -2 ×(3/3^7)
a8 = -2×(1/3^6)
a8 = (-2)/[ 3^6 ]
Yes I have graphed them and they form a 90 degree angle
Answer:40( fourty) is the answer
Step-by-step explanation:
Because they're consecutive, it means that the first one is x, the second one is x+1, the third one is x+2 (x+1+1), and the fourth one is x+3. Because we're given that the sum of all of them is 682, just add all of them together:
x+(x+1)+(x+2)+(x+3)=682
x+x+x+x+1+2+3=682
4x+6=682
4x+6-6=682-6
4x=676
x=676/4
x=169
Thus, the consecutive integers are: 169, 170, 171, 172
