I don't understand this question. If we say each term increases by 2 (n=2), we get can get almost any value in the answer choices. For example 31 + 33 = 64 or 39 + 41 = 80
kchen1994Actually each term is not increasing by 2, it is increasing by the term n, said that
a_1 = 1
a_2 = a_1 + 2
a_3 = a_2 + 3
a_4 = a_3 + 4
So if you go on in this series you will notice that pattern, if you calculate the individual terms and add a_7 and a_8 you can get the answer as B
