Question

Using the following expression: 4n - 2, where n represents the position of the term in the sequence, find the first four terms in the sequence. (HINT: put 1, 2, 3, and 4 for the term numbers in place of n)

Answer 1

2, 6, 10, 14

Explanation:

For the first term, T1

n = 1

4n - 2 = 4 * 1 - 2

= 4 - 2

= 2

Second term, T2

n = 2

4*2 - 2

= 8 - 2

= 6

Third term T3

n = 3

4*3 - 2

12 - 2

= 10

Forth term T4

n = 4

4*4 - 2

= 16 - 2

= 14

Hence, the first four terms are 2, 6, 10, 14
