What is the equation of an arithmetic sequence with a first term of 6 and a second term of 2?

The equation of the sequence = 10 - 4n

Step-by-step explanation:

The rule of the arithmetic sequence is Tn = a + (n - 1) d

Where a is the first term, d is the difference between each consecutive terms and n is the position of the number in the sequence

∵ First term = 6

∵ Second term = 2

∴ The difference between the second and the first = 2 - 6 = - 4

∴ Tn = 6 + (n - 1) (-4) = 6 - 4n + 4 = 10 - 4n

∴ The equation of the sequence = 10 - 4n
