The numbers are in arithmetic progression.
First term = 2
common difference = 3
Let, nth term be = 266
nth term = 2 + (n − 1)3
266 = 2 + 3n − 3
3n = 266 − 2 + 3 = 267
Therefore, n = 267/3 = 89
Given an arithmetic sequence with first term a and the common difference d, the nth term is given by
nth term = a + (n − 1)d
