Find the first four terms of the sequence 4n-3, where n represents the position of a term in the sequence. Start with n=1.

To find the 1^st term, plug in n=1.
4n-3=4(1)-3=4-3=1

To find the 2^nd term, plug in n=2.
4n-3=4(2)-3=8-3=5

To find the 3^rd term, plug in n=3.
4n-3=4(3)-3=12-3=9

To find the 4^th term, plug in n=4.
4n-3=4(4)-3=16-3=13

The first four terms of the sequence are 1, 5, 9, 13.

Find the first four terms of the sequence 2ⁿ, where n represents the position of a term in the sequence. Start with n=1.

To find the 1^st term, plug in n=1.
2ⁿ=2¹=2

To find the 2^nd term, plug in n=2.
2ⁿ=2²=4

To find the 3^rd term, plug in n=3.
2ⁿ=2³=8

To find the 4^th term, plug in n=4.
2ⁿ=2⁴=16

The first four terms of the sequence are 2, 4, 8, 16.
