Answer:
1,449
Step-by-step explanation:
-5 - 4 -1 4 11 20 31 subtracting:-
1 3 5 7 9 11 subtractiing:-
2 2 2 2 2
second row is 2 so the rule will contain n^2
so we can write the series as n^2 - 6 , n^2 - 8 , n^2 - 10 etc
the numbers are in arithmetical sequence with a1 = 6 and d = -2
so nth term of our sequence is n^2 - a1 + (n - 1)d = n^2 -2n - 6 + 2
= n^2 - 2n - 4 Answer

Answer:
50 marbles
Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.
4 units = 20
1 unit = 20÷4 = 5
Total = 10 units
10 unit = 5 ×10 = 50
Ans : 50 marbles
