Answer:
A) a_n = 5n + 2
B) a_n = (2^(n + 1)) - 1
Step-by-step explanation:
A) The sequence is given as;
{7,12,17,22,27,...}
The differences are:
5,5,5,5.
This is an arithmetic sequence following the formula;
a_n = a_1 + (n - 1)d
d is 5
Thus;
a_n = a_1 + (n - 1)5
Now, a_1 = 7. Thus;
a_n = 7 + 5n - 5
a_n = 5n + 2
B) The sequence is given as;
{ 3,7,15,31,63,...}
Now, let's write out the differences of this sequence:
Differences are:
4, 8, 16, 32
This shows that it is a geometric sequence with a common ratio of 2.
In the given sequence, a_1 = 3 and a_2 = 7 and a_3 = 15
Thus, a_2 = 2a_1 + 1
Also, a_(2 + 1) = 2a_2 + 1
Combining both equations, we can deduce that: a_(n + 1) = 2a_n + 1
Thus; a_n can be expressed as:
a_n = (2^(n + 1)) - 1
Answer:
The product is 3/8
Step-by-step explanation:
When you multiply two fractions, first multiply the numbers on the top (numerators).
1 * 3 = 3
Then multiply the bottom numbers (denominators).
2 * 4 = 8
Now stick the first over the second.
3/8
A equivelent ratios are just like equivelent fractions. If two ratios have the same value,then they are equivelent,even tho they may look different! A ratio table is the relation betwen two similiar magnitudes with respect to the number of times the first contains the two.
