2, 4, 13, 49, 193,

Which term should be removed so that the sequence follows the rule? Rule: Multiply the previous term by 4, then subtract 3 to produce the next term.

If we begin with the first term, 2, mult. it by 4 and then subtract 3, we get 5 (not 4, as shown).

If we begin with 4, mult. it by 4 and then subtract 3, we get 13. This agrees with the terms of the given sequence.

If we begin with 13, mult. it by 4 and then subtract 3, we get 49. This agrees with the terms of the given sequence.

Remove the first term, 2, and then the remaining terms follow the given procedure for finding terms.

2 because if you multiply by 4, then subtract 3, you get 5 not 13.
