schepotkina [342]3 years ago
5 0

Answer:

76.8

Step-by-step explanation:

Using the proportion

\frac{120}{100} → Percent is out of 100

\frac{120}{100} = \frac{n}{64} ( cross-  multiply )

100n = 7680 ( divide both sides by 100 )

n = 76.8

The 18th term of an arithmetic sequence is 49 and the first term is 15.
Tju [1.3M]

Answer:

33

Step-by-step explanation:

49-15=34

34/17=2

For this sequence, you can write this function:

f(x)=15+2(x-1)

Check:

f(18)=15+2(18-1)

f(18)=15+2(17)

f(18)=15+34

f(18)=49

So:

f(10)=15+2(10-1)

f(10)=15+2(9)

f(10)=15+18

f(10)=33
