WebThis second term is ar to the first power. The third term is ar to the third power. It looks like the nth term is going to be ar to the n minus 1 power. So ar to the n minus 1. And you could verify it. If you want the second term, you say a times r to the 2 minus 1, a times r to the first power. It works out. This is defining it explicitly.

WebOct 23, 2016 · The fifth is 10. Find the first term. In this task we have 2 terms given: a2 = 4 and a5 = 10. We can use the n −th term formula to build a system of equations: {a1 + d = 4 a1 + 4d = 10. If we subtract the first equation from the second we can calculate d: 3d = 6; d = 2. Now if we substitute the calculated value we see that: a1 + 2 = 4, so a1 = 2.
