Answer 2

Answer: A. 2748

Step-by-step explanation: From the explicit formula: an= a1 + (n -1).d

an means number of terms we are looking for.

a1 means the first term of the arithmetic progression which is 57

d means common differences between the terms. I.e second term (a2)- first term(a1). 66-57=9

Substituting the values into the formulae.

a300= 57 +(300-1)9

a300= 57 +(299×9)

= 57 + 2691

a300 = 2748
