we can check if a given sequence is geometric or not by checking the terms present in it ,
Let us find ratio of each term with it's previous term
if that ratio comes out same for every two consecutive terms then it is a geometric sequence , otherwise it is not geometric sequence .
Let us work on first one : given is : -1,1,-1,1.............
second term/ first term = 1/-1 = -1
third term/ second term = -1/1 = -1
fourth term / third term = 1/-1 = -1
fifth term/ fourth term = -1/1 = -1
because that ratio is same so it is a geometric sequence .
* let us now work with second sequence .
eE
second term/ first term = -6/-2 = 3
third term/ second term = -18/ -6 = 3
fourth term / third term = -54 / -18 = 3
hence this is also geometric sequence .
Answer : both are geometric sequence .
Answer:
The number of expected double crossover progeny is 47.275
To the nearest whole number 47
Step-by-step explanation:
Consider the provided information.
The distance between withered wings (whd) and smooth abdomen (sm) is 30.5,
That means the probability of crossover between them is 0.305.
The distance between smooth abdomen (sm) and speck body (sp) is 15.5,
That means the probability of crossover between them is 0.155
The resulting phenotypically wild-type females were mated with males that had the mutant phenotype for all three traits,
That means the expected frequency of double crossover progeny will be:
0.305×0.155 = 0.047275
It is given that they producing 1000 offspring, therefore,
0.047275×1000 = 47.275
The number of expected double crossover progeny is 47.275
To the nearest whole number 47

Step-by-step explanation:
I used the rule they gave up top. Hope this helps :)
Answer:
Step-by-step explanation:
it's going to alternate back and froth between positive and negative, maybe it will make one of those "telescoping" sequences
