1. Refer to the following sequences in R:
29 37 8
(an):= 7' 70' 35' 70' 35
(bn) := 2√6,6√2, 6√6, 18√2, 18√6, 54√2,...
(cn): 8, 1.04, 1.352, 1.7576, 228.488,...
(dn): -2.3,-0.2, 1.9, 4, 6.1, ...
(en): 1, 2, 4, 7, 28, 33, ...
Take two arithmetic sequences from the list above
and show that as sets, these two are equinumerous.
Hint: Assume that the terms of each sequence are the elements of sets X and Y,
respectively. Then, define a function f: X->Y and prove that f is bijective.
