Question

find the nth term  of the following sequence
-7 ,-4   , -1  ,  2  ,5​

Answer 1

Answer:

3n - 10

Step-by-step explanation:

Find the difference between the terms

-7 , -4 , -1,  2,  5  

  +3   +3   +3  +3

Difference of terms = 3,  so you'd write that as 3n  

Then you'd need to find the difference between the 1st term and 3:  

3 > -7

  - 10

So you'd write that as 3n - 10
