Question

Tn=2(n-1)
Given the formula for the nth term, state the first 5 terms of each sequence.

Answer 1

0, 2, 4, 6, 8

Explanation:

substitute 1 for n in first term, 2 for n in second term, 3 for n in third term, 4 for n in fourth term, 5 for n in fifth term

2 (1) -2 = 0 first term

2 (2)-2 = 2 second

2 (3)-2 = 4 third

2 (4)-2 =6 fourth

2 (5)-2 =8 fifth
