Question

4. Consider the sequence 17/7, 20/7, 23/7.... a) Write the algebraic expression b) Write the sequence of counting numbers in the above given sequence. Is the newly obtained sequence is an arithmetic sequence?

Answer 1

Answer:

an = a1 + (n-1)r

14/7

Yes

Step-by-step explanation:

r = 20/7 - 17/7

r = (20-17)/7

r = 3/7

an = a1 + (n-1)r

17/7 - 3/7

(17-3)/7

14/7
