Answer:
The equation for nth term is 3n + 5.
Step-by-step explanation:
Let a1 be a,
a3 = a + (n - 1)d
or, 14 = a + (3 - 1)d
so, 14 = a + 2d
Now,
a5 = a + (n - 1)d
or, 20 = a + (5 - 1)d
or, 20 = a + 4d
now,
a + 4d = 20
a + 2d = 14
now,
a + 4d - ( a + 2d) = 20 - 14
or, a + 4d - a - 2d = 6
or, 2d = 6
so, d = 3
Now,
a + 2d = 14
or, a + 2(3) = 14
or, a = 14 - 6
so, a = 8
Now,
an = a + (n - 1)d
or, an = 8 + (n - 1)3
or, an = 8 + 3n - 3
so, an = 3n + 5
Answer:
d: 56
e: 68
f: 56
Step-by-step explanation:
First, we can start off with a fraction:
9/36 = 1/4
Now that we have this fraction, we multiply by 25:
25/100
This can be changed into a percent:
25%
100 - 25 = 75
25% is alcohol and 75% is water
Answer:
a ) Square Root of 25 = 5
b ) Square Root or 81 = 9
c ) Square Root of 64 = 8
d ) Square Root of 169 = 13
