a = 1
d = 2
L = 49
=> a + (n-1)d = 49
=> 1 + (n-1) (2) = 49
=> (n-1) (2) = 48
=> n - 1 = 24
=> n = 25
Required sum = n/2 [ a + L]
= 25 / 2 [ 1 + 49]
= 25 × 50 / 2
= 25 × 25
= 625
d = 2
L = 49
=> a + (n-1)d = 49
=> 1 + (n-1) (2) = 49
=> (n-1) (2) = 48
=> n - 1 = 24
=> n = 25
Required sum = n/2 [ a + L]
= 25 / 2 [ 1 + 49]
= 25 × 50 / 2
= 25 × 25
= 625
