Take a guess that the answer is a line.
Use any to points where the term number is x and the term value is y. Sove for the slope and intercept.
Terms 2 and 4 would give:
m * 2 + b = 10
m * 4 + b = 18
m = (18  10) / (4  2) = 8 / 2 = 4
If m = 4, what is b? (just substitute)

The 100th term will be:
100 * m + b
m = 4 and b = ?
The 100th term is 402
