Answer:
a. 12,15,18,21
b. -1,3,5,7
c. -3,-5,-7,-9
Step-by-step explanation:
Just subtitute the terms sa N
TERM A. [3n + 6]
1st Term: 3n + 6 = 3 (1) + 6 = 3 + 6 = 9
2nd Term: 3n + 6 = 3 (2) + 6 = 6 + 6 = 12
3rd Term: 3n + 6 = 3 (3) + 6 = 9 + 6 = 15
4th Term: 3n + 6 = 3 (4) + 6 = 12 + 6 = 18
5th Term: 3n + 6 = 3 (5) + 6 = 15 + 6 = 21
TERM B. [2n - 3]
1st Term: 2n - 3 = 2 (1) - 3 = 2 - 3 = -1
2nd Term: 2n - 3 = 2 (2) - 3 = 4 - 3 = 1
3rd Term: 2n - 3 = 2 (3) - 3 = 6 - 3 = 3
4th Term: 2n - 3 = 2 (4) - 3 = 8 - 3 = 5
5th Term: 2n - 3 = 2 (5) - 3 = 10 - 3 = 7
TERM C. [-2n + 1]
1st Term: -2n + 1 = -2 (1) + 1 = -2 + 1 = -1
2nd Term: -2n + 1 = -2 (2) + 1 = -4 + 1 = -3
3rd Term: -2n + 1 = -2 (3) + 1 = -6 + 1 = -5
4th Term: -2n + 1 = -2 (4) + 1 = -8 + 1 = -7
5th Term: -2n + 1 = -2 (5) + 1 = -10 + 1 = -9
