Question

Determine the nth term of the sequence 2,4,6,8​

Answer 1

Answer:nth term=2n

Explanation:

first term(a)=2

Common difference(d)=4-2=6-4

Common difference(d)=2

nth term=a+d x (n-1)

nth term=2+2 x (n-1)

nth term=2+2n-2

Collect like terms

nth term=2-2+2n

nth term=0+2n

nth term=2n

Answer 2

1. Find the difference ( diff is 2 )

2. Apply the concept diN+0 (more easier use this :) )

* di is difference

* N is nth term

* 0 is first term - difference

3. Find 0

- first term (2) - difference (2) = 0

answer: 2n
