The nth term of a sequence is represented by 3 ... - WAEC Mathematics 1998 Question
The nth term of a sequence is represented by 3 x 2(2-n). Write down the first three terms of the sequence
A
3/2, 3, 6
B
6, 3, 3/2
C
3/2, 3, 1/3
D
2/3, 3, 8/3
correct option: b
When n = 1, n = 2, n = 3
3 x 22 - 1 = 6
3 x 22 - 2 = 3
3 x 22 - 3 = 3/2
3 x 22 - 1 = 6
3 x 22 - 2 = 3
3 x 22 - 3 = 3/2
