F(n)=25 f(n)=f(n-1) what are the first four terms of the sequence

f(1) = 2 and f(2) = 7

f(n) = f(n-1) + 2f(n-2) for n ≥ 3

So, for n = 3, we have f(3) = f(2) + 2f(1) = 7 + 4 = 11

When n = 4, f(4) = f(3) + 2f(2) = 11 + 14 = 25

First four terms:  2, 7, 11, 25

Step-by-step explanation:

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
