Question

the sum of first 10 terms of an ap is 175 and the sum of next terms is 475 then find the ap​

Answer 1

Answer:

4, 7, 10and so on

Step-by-step explanation:

sum of first 10 terms is 175

so 10a + 45d = 175 ....(1)

sum of next 10 terms is 476

so 10a + 145d = 475 ....(2)

from (1) and (2)

100d = 300

d = 3

if we substitute d=3 in (1)

a = 4
