Answer:
260 seashells
Step-by-step explanation:
If there are 50 seashells on the beach and after one week there are 120 seashells on the beach and this same pattern continues, then the number of sea shells form weekly will form an arithmetic progression.
The sequence formed will be;
50,120...
To find the number of seashells that we will have in the 4th week is equivalent to finding the 4th term of the sequence.
The formula for calculating the nth term of a sequence is as given below;
Tn = a+(n-1)d where;
a is the first term
n is the number of terms
d is the common difference.
According to the sequence;
a = 50,
d = 120-50 = 70
n = 4 (since we are looking for the 4th term)
Substituting this values in the given formula we have;
T4 = 50+(4-1)70
T4 = 50+3(70)
T4 = 50+210
T4 = 260
This means that there will be 260seashells on the 4th week if the same pattern continues.

If it's math then 6 3/6 would be a mixed number
The correct answer is 2.5. Not too sure how to get that answer but my math test had this question and that was the answer.
Answer:
The minimum number of fish each must have caught is 90 fishes
Step-by-step explanation:
The number of fishes Tisha's net can hold = 15
The number of fishes Dana's net can hold = 18
Let the total number of fishes both Tisha and Dana caught = X
15 × A = 18 × B = X
Therefore, X is the lowest common multiple (LCM) of 15 and 18 given as follows;
15 = 3 × 5
18 = 3 × 6
Therefore, the LCM of 18 and 5 = 3 × 5 × 6 = 90
Which gives, the minimum number of fish each must have caught = 90 fishes.
