Question

List the rst 10 terms of each of these sequences. a) the sequence obtained by starting with 10 and obtaining each term by subtracting 3 from the previous term b) the sequence whose nth term is the sum of the rst n positive integers c) the sequence whose nth term is 3n −2n d) the sequence whose nth term is√n e) the sequence whose rst two terms are 1 and 5 and each succeeding term is the sum of the two previous terms

Answer 1

Answer:

a) 10, 7, 4, 1, -2, -5, -8, -11, -14, -17.

c)  1, 2, 3 4 5 6 7 8 9 10.

d) √1 , √2, √3  √4 , √5, √6  √7 , √8, √9 √10.

e)     1, 5, 6, 11, 17, 28, 45, 73, 118, 191.

Step-by-step explanation:

a)  10, 10-3 , 10-3-3...

c)  3(1)- 2(1) , 3(2) - 2(2), 3(3) - 2(3),  3(4) - 2(4) ..

= 1, 2, 3, 4...

d) √1 , √2, √3 ...

e)  1, 5,  (5+6), (5 + 11)...
