Step-by-step explanation:
An arithmetic sequence is a sequence that adds or subtracts the same amount every time, making the answer C. The numbers are increasing by +5 consistently.
Formula of the sum of the 1st nth term in a Geometric Progression:
Sum = a₁(1-rⁿ)/(1-r), where a₁ = 1st term, r = common ratio and n= rank nth of term (r≠1)
Sum = (-11)[1-(-5⁸)] /[(1-(-5)]
Sum = (-11)(1- 390625)/(6)
SUM = 716,144
6*6 =36
14/2 =7
36+7= 43
100-82= 18
43 > 18
therefore A is truw
Answer: Nine less than two thirds of a quantity is smaller than one more than that same quantity.
The answer would be c because 1-5-7 is the same as 5-8
