Answer: Equals a+ (n-1)d Equals 2n-1 for AP
a1 = 2-1 Equals 1
a2 = 4-1 = 3
d = 3-1 = 2 is the common difference.
The sum of n terms is (n/2)(2a + (n-1)d).
= (n/2)(2+(n-1)2)
= (n/2)(2+2n-2)
= (n/2)2n
= n2
If the nth Term of an AP be 2n – 1 then the Sum of its First n Terms will be
If the nth term of an ap be 2n 1 then the sum of its first n terms will be- Find the answer to this question and access a vast question bank that is customized for learners.
