Step-by-step explanation:
in an arithmetic sequence any new term is created by adding a defined constant to the previous term.
a1 = 2
the defined constant to be added = common difference = a2 - a1 = 11
so,
a2 = 2 + 11 = 13
a3 = a2 + 11 = a1 + 2×11 = 2 + 22 = 24
a4 = a3 + 11 = a1 + 3×11 = 2 + 33 = 35
