To find the first term of the sequence, we substitute n = 1 into the formula:
A(1) = -5 * 3(1) - 1 = -5 * 3 - 1 = -15 - 1 = -16
Therefore, the first term of the sequence is -16.
To find the fourth term of the sequence, we substitute n = 4 into the formula:
A(4) = -5 * 3(4) - 1 = -5 * 12 - 1 = -60 - 1= -61
Therefore, the fourth term of the sequence is -61.
To find the eighth term of the sequence, we substitute n = 8 into the formula:
A(8) = -5 * 3(8) - 1 = -5 * 24 - 1 = -120 - 1 = -121
Therefore, the eighth term of the sequence is -121.
A(1) = -5 * 3(1) - 1 = -5 * 3 - 1 = -15 - 1 = -16
Therefore, the first term of the sequence is -16.
