lima suku pertama dari rumus suku ke,-n Un=2'n-1' + n² adalah ... mohon bantuannya...

Un = 2^n-1 + n^2

U1 = 2^1-1 + 1^2 = 2
U2 = 2^2-1 + 2^2 = 6
U3 = 2^3-1 + 3^2 = 13
U4 = 2^4-1 + 4^2 = 24
U5 = 2^5-1 + 5^2 = 41

Un = 2^(n - 1) + n^2
U1 = 2^(1 - 1) + 1^2 = 2^0 + 1 = 1 + 1 = 2
U2 = 2^(2 - 1) + 2^2 = 2^1 + 4 = 2 + 4 = 6
U3 = 2^(3 - 1) + 3^2 = 2^2 + 9 = 4 + 9 = 13
U4 = 2^(4 - 1) + 4^2 = 2^3 + 16 = 8 + 16 = 24
U5 = 2^(5 - 1) + 5^2 = 2^4 + 25 = 16 + 25 = 41
Jadi 5 suku pertamanya adalah = 2, 6, 13, 24, 41
