Write a formula for this sequence: 8, -1, -10, -19,...

Write a formula for this sequence: 8, -1, -10, -19,...

Write an expression for the sequence: 10, 17, 24, 31,...

What is the common difference in this sequence? 10, 17, 24, 31,…

Answer 1

Give the next two numbers in the pattern. 4, 8, 12, 16,...

Answer 2

Give the next two numbers in the pattern. 0, 0.75, 1.5, 2.25, ..

Answer 3

3.code
\(\large\tt \begin{align} \color{black}{9, 4, -1, -6,.....\\~\\
\text{in this sequence the the pattern is showing the}\\
\text{common difference of -5}\\
4-9=-5\\
-1-4=-5\\
-6-(-1)=-5\\
\text{this is AP sequence}
}\end{align}\)

Answer 4

These are all arithmetic sequences - which means that you add (or subtract) the same number to move to each next step

In the first one 9,4,-1,-6 yo u can see that each step adds -5 to the previous.

To get the next two steps just carry on from -6, simply add -5, then -5 again...

All the others are similar - look for the difference between two adjacent steps - it is the same for all steps in that question

Answer 5

for the first sequence :- 5 is subtracted to get next term

Answer 6

-11, -16 ?
