Question

if the common difference of A.P is 2, then a10 -a5 is​

Answer 1

Step-by-step explanation:

Given: common difference of A.P is 2

i. e. d = 2

We need to find the value of:

a_{10}-a_5

Now,

$a_{10}-a_5 \\ = \{a + (10 - 1)d \} - \{a + (5 - 1)d \} \\ = \{a + 9d \} - \{a + 4d \} \\ = a + 9d - a - 4d \\ = 5d \\ = 5 \times 2 \\ = 10 \\ thus \\ \huge \boxed{a_{10}-a_5 = 10}$

Answer 2

Step-by-step explanation:

a10-a5=10 is the answer......
