Question

What is the next term of the arithmetic sequence? -7,-3,1,5,9,

Answer 1

Explanation:

The first term (a) = -7

common difference= -3-(-7)= -3+7= 4

The next term i.e. 6th term

a6= a+5d

= -7+5(4)= -7+20= 13

Answer 2

The next term is 13.

Explanation:

Looking at the previous numbers...

for -7 to get to -3, you have to add 4, and for -3 to get to 1 you have to add 4.... and so on. So in order to find the next number, add 4 to 9, and which you get 13.
