1, 4, 9, 16, 25, 36, 49, 64 _ ?

1, 4, 9, 16, 25, 36, 49, 64 _ ?

 

Answer:

81

Step-by-step explanation:

Each number is added by an odd numbers

Starting from 3

The odd numbers that are starting from no. 3 are

{3,5,7,9,11,13,15,17...}

So it would be

64 + 17 = 81

What Is The Sum Of The Infinite Geometric Series 3/4 -9/16+27/64 -81/256+ ...?, A. 3 , B. 1 , C. 3/4, D.3/7

What is the sum of the infinite geometric series 3/4 -9/16+27/64 -81/256+ ...? a. 3 b. 1 c. 3/4 D.3/7   Geometric Sequence Finding the sum The sum of the infinite geometric series 3/4 -9/16+27/64 -81/256+ . ..is 3/7. Solution: Geometric Series Sum Formula: S = a₁/1 - r Given: a₁ = 3/4            a₂ = -9/16            a₃ = 27/64            a₄ = -81/256 1. Find the common ratio.        a_n = a₁r ⁿ ⁻ ¹         a₂  = a₁r ⁿ ⁻ ¹    -9/16 = 3/4 r ² ⁻ ¹    -9/16 = 3/4 r 2. Divide both sides of the equation by 3/4 to find r.     -9/16/3/4 = 3/4 r/3/4   (-9/16)(4/3) = r         -36/48 = r             -3/4 = r 3. Using r = -3/4, find the sum of the infinite geometric series 3/4 -9/16 +27/64 -81/256+ ...     S = a₁/1 – r     S = 3/4/1 – (-3/4)     S = 3/4/1 + ¾     S = 3/4/4/4  + 3/4     S = 3/4/7/4     S = (3/4)(4/7)     S = 12/28     S = 3/7 4. Therefore, the sum of the infinite geometric series 3/4 -9/16+27/64 -81/256+ ...is 3/7. Defin...

What Is The Next Number? What Is The 12th Number? 1, 3, 9, 27, 81, _____

What is the next number? What is the 12th number? 1, 3, 9, 27, 81, _____   Answer: The next number is 243. Therefore, the sequence is 1, 3, 9, 27, 81, 243 . Step-by-step explanation: To determine the answer, you have to find the rule or pattern that is being applied in the sequence. If you could notice, the next number is always the product of 3 and the previous number. For example, 81 is the product of 3 and 27. 27 is the product of 3 and 9. 3 is the product of 3 and 1. Therefore, the next number in the sequence should be the product of 3 and 81. 81 x 3 = 243. The answer is 243, and the complete sequence is 1, 3, 9, 27, 81, 243 . That is the answer for the given question.

Alfred Wegener Is A German Scientist Who Hypothesized That The Earth Was Once Made Up Of A Single Large Landmass Called Pangaea. Which Of The Followin

Alfred Wegener is a German scientist who hypothesized that the Earth was once made up of a single large landmass called Pangaea. Which of the following theories did Wegener propose? a. Continental Drift Theory b. Continental Shift Theory c. Plate Tectonics d. Seafloor Spreading Theory   Answer: The correct answer is letter a. Continental Drift Theory. Explanation: The theory that Alfred Wegener propose is the  Continental Drift Theory. It  Hypothesized that continents were once a large supercontinent that drifted apart from each other. This was largely unaccepted in the northern hemisphere where geologists don not believe that rock movements of that type could happen. This was widely accepted by the geologists in the southern hemisphere. Some of the proofs that Wegener used in the continental drift theory were: The fit of the continents. Distribution of fossils wherein same species were discovered on different continents. Glaciation on some continents at same period in th...
