Use the geometric series formulas to find the sum of the geometric series.
1 + √3 + 3 + 3√3 + ⋯ + 243

573.578

Step-by-step explanation:

Geometric Sequence is the sequence in which every digit is the same multiplier of its previous digit.

The given Sequence is: √3 + 3 + 3√3 + ⋯ + 243

here a₁ = √3, r = 3 ÷ √3 = √3.

First we will find the number of terms for this we use formula:

⇒ 243 = √3(√3)ⁿ⁻¹  

⇒ (√3)¹⁰ = √3(√3)ⁿ⁻¹

⇒ (√3)⁹ = (√3)ⁿ⁻¹

⇒ n - 1 = 9

⇒ n = 10

The formula of sum of geometric series is:

⇒

⇒ Sₙ = 572.578147716

Thus the sum of 1 + √3 + 3 + 3√3 + ⋯ + 243 = 1 + 572.578 = 573.578

step-by-step explanation:

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?
