Consecutive Integers

Duration: 15m 44s

The video, "Integers Pt 6 – Consecutive Integers," explores how to identify and represent consecutive, even, and odd integers using algebra. You’ll learn patterns for summing consecutive numbers, how to handle odd- and even-length sets, and useful shortcuts for calculating sums and products. The video also highlights GMAT-relevant properties—such as when sums are divisible by the number of terms or when products are guaranteed to be even or divisible by 8.
