Consider the sequence 130, 143, 156, 169, ... Write an explicit formula to represent the arithmetic sequence and use it to find

pantera1 [17]

Answer:

a(n) = 130 + (n-1) 13

13th term = 286

Step-by-step explanation:

We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.

We know that the arithmetic sequence can be defined by:

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

where $d$ = the common difference between consecutive terms ; and

$c$ = $a_1$

13th term:

$a_{13}=130+(12)13 = 286$

Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.

Matthew has a bag of green & yellow skittles. There are 38 total in the bag.

olya-2409 [2.1K]

Solution:

As per the problem we have

Matthew has a bag of green & yellow skittles. There are 38 total in the bag.

If g = green Skittles & y = yellow Skittles,

Then, sum of the two skittles will be equal to 38

which means $g+y=38$

Hence, the equation representing the given data can be written as :

Hence , option B, $g+y=38$
