Penjelasan dengan langkah-langkah:

rasio

r = U2/U1

r = 4/2 = 2

un = ar^ⁿ⁻¹

un = 2.2ⁿ⁻¹

un = 2. 2ⁿ. 2⁻¹

un = 2. 2ⁿ . 1/2

un = 2/2. 2ⁿ

un = 1. 2ⁿ

un = 2

opsi c

Pola barisan geometri: 2, 4, 8, 16, ...

r = U2 ÷ U1

r = 4 ÷ 2

r = 2

Bentuk persamaan-nya:

Un = ar^n - 1

Un = 2 × 2^n - 1

Un = 2 × 2^n × 2^-1

Un = 2 × 2^n × 1/2¹

Un = 2 × 2^n × 1/2

Un = 2 ÷ 2 × 2^n

Un = 1 × 2^n

Un = 2^n
