How to erite a sequence of 1/4 , 1/2,3 write a rule for the sequence 1/4 1/2 3/4

FrozenT [24]

The equation for finding the equation of an arithmetic sequence is an=a1+(n-1)d, where n is the input for the sequence, a1 is the first term, and d is the difference between each term.

a1= 1/4
d= 1/4

an= 1/4 + (n-1)(1/2) - First you need to distribute the 1/2 to both the n and -1 to get: an= 1/4 + 1/2n -1/2.

Then you need to add like terms (1/4-1/2) to get an=1/2n-1/4. Hope this helps!

The sales of homes in a new development have been increasing. In January, 5 homes were sold, in February,

Rama09 [41]

Answer: $a_n=7n-2$

Step-by-step explanation:

Let we consider sales of home in January as first term for sequence, then sales in February will be 2nd term and so on.

According to the given information, we have

First term : $a_1=5$

Second term : $a_2= 12=5+7$

Third term : $a_3= 19=12+7$

We can see that, Common difference = 7

Explicit rule for Arithmetic sequence :

$a_n=a_1+(n-1)d$

Put $a_1=5$ and d=7

$a_n=5+(n-1)7\\\\ a_n=5+7n-7\\\\ a_n=7n+5-7\\\\ a_n=7n-2$

The required explicit rule that can be used to find the number of homes sold in the nth month of the year : $a_n=7n-2$
