Question

What is the recursive and explicit formula for the following arithmetic sequence:
2, -4, -10, -16, -22,...

Answer 1

Answer:

the above sequence is in arithmetic progression

Step-by-step explanation:

the formula is a+(n-1)d

a=first term

n=number of terms

d=common difference

For instance you have to find the fourth term

n=4 ; a=2; d= -6

a+(n-1)d

2+(4-1)*-6

2+3*-6

2-18

=-16

use this formula for whichever term you wanna find in this sequence ( a+(n-1)d )
