Question 1 1.1 Given the quadratic number pattern: 5; 10; 17; 26;.. 1.1.1 Write down the next TWO terms of the pattern. 1.1.2 D
vitfil [10]

The next two terms of the sequence based on the information given is 37 and 50.

<h3>How to illustrate the sequence?</h3>

It should be noted that from the information given, the numbers illustrated are 5, 10, 17, and 26.

In this case, there is an addition of 2 to the previous difference.

Therefore, 26 - 17 = 9.

The next number will be:

= 26 + 9 + 2 =37

The following number will be:

= 37 + 11 + 2

= 50

Find the 91st term of the arithmetic sequence 28, 8, -12, ...
lesya692 [45]

Answer:

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

a_n=a_1+d(n-1)

where n is the position of the number in the sequence, a1 is the first number in the sequence, and d is the common difference between the numbers.  

If we are looking for the 91st term, our n = 91;

our a1 is 28, and

the common difference is -20.  Putting all that together gives us the explicit formula for this sequence:

a_{91}=28-20(91-1) and

a_{91}=28-20(90) and

a_{91}=28-1800 so

a_{91}=-1772
