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) ...
