Answer:
1275
Step-by-step explanation:
The natural numbers 1, 2, 3, 4, ...... , 49, 50
The terms of natural numbers are the terms of an arithmetic sequence.
The sum to n terms of an arithmetic sequence is
• =
[2a + (n- 1)d ]
where a is the first term and d the common difference
here a = 1, d = 1 and n = 50, hence
=
[ 2 + (49 × 1) ]
= 25(2 + 49) = 25 × 51 = 1275
