A sequence in which every term is equal to the sum of its preceding term and constant is called an arithmetic sequence. In the following options, which are in arithmetic sequences if a, b, c, d, e are in arithmetic sequence?

A. \(2_a, 2_b, 2_c, 2_d, 2_e\)

B. \(2–10_a, 2–10_b, 2–10_c, 2–10_d, 2–10_e\)

C. \(a+2, b+3, c+4, d+5, e+6\)

D. \(a^2, b^2, c^2, d^2, e^2\)
