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
