Without knowing anything about the sequence, this is impossible to answer. But suppose the sequence is arithmetic, in which case each term differs by some constant
:





Then we can write

and from the formula above, we see this means the 10th term in the sequence is
. But that's all the specific info we can gather about such an arithmetic sequence. If we set the first term to be some unknown
, then the sum of the first 19 terms in the sequence would be

If we knew one more term in the sequence, we could determine the value of
and derive the value of
(if the first term
is not immediately given), and then go on to find an exact numeric value for the sum.
Answer:
A=discrete; B=continuous
Step-by-step explanation:
(a) The number of free dash throw attempts before the first shot is = discrete
(b) The time it takes for a light bulb to burn out.=continuous
Discrete variables are countable in a finite amount of time such as the case of free dash throw attempts
Continuous Variables are more difficult to count. In statistics, time is a Continuous Variable
(3+6X(5+4)÷3-7) the answer is 14
Answer: b= 58a (divided 348 by 6 and take the equation b = ka and substitute k with 58)
