Answer 1

Answer:

Is the sequence arithmetic, does it add the same thing every time? If so take the first term and add 99 times the common difference (the number being added each time).

Example: 5, 18, 31, 44, … The common difference is 13. 5 + 99(13) = 1292

Is the sequence geometric, does it multiply by the same thing every time? If so take the first term and multiply by the common ratio (the number multiplied by each time) to the 99th power.

Example 13, 39, 117, 351, … The common ratio is 3. 13 x 3⁹⁹ = 2.333 x 10⁴⁸
