Question

Match the following arithmetic sequence to the 10th term and the rule by drawing a line from one column to the next one

Answer 1

`\left[\begin{array}{cccccccc}1, 4, 7, 10&28&3n-2\\2,8,14,20&56&6n-4\\18,14,10,6&-18&22-4n\\-4,-1,2,5&23&-7+3n\\0.1,0.4,0.7,1&2.8&0.3n-0.2\\9,11,13,15&27&9+2(n-1)\\-0.8,-1,-1.2,-1.4&-2.6&-0.2n-0.6\\5,15,20,25&50&5n\end{array}\right]`

Explanation:

Use the arithmetic sequence to find the answers:

`a_(n)=a_(1)+d(n-1)`

a1 = first number

d = common difference

n = term you want to obtain (10 in this case)

Hope this helps!
