Question

Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.

14, 18, 22, 26, 30, ...

Answer 1

4n+10

Answer 2

how did u get that?

Answer 3

1st term is 14 so a(1)+B=14. then a(2)+B=18, it continues linearly so it can be solved as this simple set of linear equations. Basically solve for a and b given the first two equations.

Answer 4

10+4(1),10+4(2),10+4(3),10+4(4),10+4(5),...,10+4n
