Answer 2

Answer:

39900

Step-by-step explanation:

》Let's form an AP of the given data in order to get the correct answer

A.P. = 504,511,...,896

a1 = 504

a2 = 511

d = a2 -a1

d = 511 -504

d = 7

an = 896

an = a+(n-1)d

896 = 504 +(n-1)7

896 = 504 +(n-1)7

(n-1)7 = 896 -504

(n-1)7 = 392

(n-1) = 392 /7

(n-1) = 56

n = 56 +1

n = 57

Sn = n/2 (a+an)

S57 = 57/2 (504 + 896)

S57 = 57/2 (1400)

S57 = 57 ×700

S57 = 39900
