A is answer
The sum of the geometric series 2⁰ + 2¹ + 2² + 2³ + 2⁴ + … + 2⁹ is 1023 after applying the sum formual for geometric sequence option (a) 1023 is correct.
What is a sequence?
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a geometric sequence is given:
2⁰ + 2¹ + 2² + 2³ + 2⁴ + … + 2⁹
The first term of the geometric sequence:
a = 2⁰ = 1
The common ratio:
r =2¹/2⁰
r =2
The sum can be evaluated using the formula:
S = a(rⁿ - 1)/(r-1)
n = 10
S = 1(2¹⁰ - 1)/(2-1)
S = 1024 - 1
S = 1023
Thus, the sum of the geometric series 2⁰ + 2¹ + 2² + 2³ + 2⁴ + … + 2⁹ is 1023 after applying the sum formual for geometric sequence option (a) 1023 is correct.
