Homework
Get the method.
Snap the problem. Grabo breaks it down and gives you one hint at a time: you find the answer, and you can do the next one on your own.
Find u₇ for the arithmetic sequence with u₀ = 3 and r = 2.
Between u₀ and u₇, how many times do you add r?
7 times! So u₇ = 3 + 7 × 2 = 17
That’s it: you found the method.
