Question

tell whether the sequence below is arithmetic if it is whats the common difference 2, 7, 13, 20? i need help!

Answer 1

the Answer is no the sequence is not arithmetic

Explanation:

the sequence 2, 7, 13, 20 is not have a number in common here i will show you.

try adding 2 plus 5 you get 7 but you add 5 to7 you do not get 13 you get 12 so that is not the number in common.

now try 2 plus 6 you get 8 so that is not it

now try 2 plus 2 you get 4 so that is not it

so all that is left is the sequence is not arithmetic. Your Welcome

Answer 2

The sequence is 5, 6, 7. It is not arithmetic because it is not the same number in order- 3, 3, 3 so there is no common difference
I got that by subtracting 2 from 7 and I got 5 I subtracted 7 from 13 and got 6 I subtracted 13 from 20 and got 7
Hope this helps you!! :)
