Question

This is an example of an arithmetic series: 6 + 8 + 10 + 12 + . . . + (4 + 2n) + . . .

True
False

Answer 1

true, because there is always a constant difference between the terms.
ex: 8-6 = 10-8 = 12-10 = 2

Answer 2

Thank you!

Answer 3

Use :

\[\large a_n = a + (n-1)d\]

Answer 4

Here a = 6 and d = 8 - 6 = 2

\[a_n = 6 + (n-1)2 \implies 4 + 2n\]

It is an Arithmetic Progression..
