Answer:
The given sequence is t
n
=2n−1.
The first term t
1
can be determined by substituting n=1 in the sequence t
n
=2n−1 as follows:
t
1
=(2×1)−1=2−1=1
The second term t
2
can be determined by substituting n=2 in the sequence t
n
=2n−1 as follows:
t
2
=(2×2)−1=4−1=3
The third term t
3
can be determined by substituting n=3 in the sequence t
n
=2n−1 as follows:
t
3
=(2×3)−1=6−1=5
Hence, the sequence is 1,3,5,
