Summary
The essence of arithmetic sequences is explored, highlighting their definition, the formula for finding any term in the sequence, and practical applications in solving GMAT problems.
- An arithmetic sequence is defined by the addition of a constant difference to go from one term to the next.
- The formula for finding the nth term of an arithmetic sequence is a_n = a1 + (n-1)d, where a1 is the first term and d is the common difference.
- Special cases of arithmetic sequences include consecutive integers, consecutive odd or even numbers, and sets of numbers that share a common remainder when divided by a particular divisor.
- Understanding the underlying concept of arithmetic sequences and the derivation of their general formula is crucial for solving related GMAT problems.
- Practical examples illustrate how to apply the formula to find specific terms within a sequence and solve typical GMAT questions.
