The answer is 91/10
Step-by-step explanation:
hope this helps
Solutions:
2 3/5÷2/7
13/5÷2/7
13/5×7/2
=13×7=91
=5×2=10
That's why the answer is 91/10
First, we inspect what type of sequence is the order of the coordinates:
a2 = 1
a3 = 2
a4 = 4
Getting the difference,
a3 - a2 = 1
a4 - a3 = 2
The differences are not equal; hence, the sequence is not arithmetic.
Getting the ratio:
a3/a2 = 2
a4/a3 = 2
The common ratio is 2. Using the general form for a geometric series:
an = a1 r^(n-1)
If n = 2
1 = a1 (2)^(2-1)
a1 = 1/2
So,
an = (1/2) (2)^(n-1)
The answer is the first option.
3 was gold 15 left bronze is twice of silver then bronze is 10 medals
