Question

plz answer this quick!!!​

Answer 1

Step-by-step explanation:

S50= n/2 { 2a + (n-1) d}

S50 = 25 { 2 + ( 50 - 1 ) 1}

S50 = 25 ( 2 + 49)

S50 = 25 ×51

.: S50 = 1275

Thus option B is correct.

Answer 2

the natural numbers are start with 1,2,3,......50

this forms an arthematic progression so

a=1,d=2-1=1 n=50

s50=50/2[2(1)+(50-1)1]

=25[2+49]

=25[51]

=1275

option b is correct
