The terms in the sequence increases by 7.
2 + 7 = 9
9 + 7 = 16
16 + 7 = 23
To find out the 50th term in the sequence, we can look at the following pattern:
1st term = 2 = 0(7) + 2
2nd term = 9 = 1(7) + 2
3rd term = 16 = 2(7) + 2
Therefore, the 50th term is 49(7) + 2 = 345.
We are trying to find the nth term, such that (n - 1)(7) + 2 = 695.
Subtract 2 on both sides:
(n - 1)(7) = 693
(n - 1) = 99
n = 100
Hence, the number 695 is the 100th term in the sequence.
