Question

please say the answer​

Answer 1

Answer:

Explanation:

(a) We know nth term of an arithmetic sequence is given by

an = a + (n - 1) d

an = a + dn -d

As we can see coefficient of n is the common difference,

d = 3

And,

a - d = 5

a - 3 = 5

a = 8

(b) a10 = 3 * 10 + 5

           = 30 + 5

           = 35

Or,

a10 = 8 + 9 * 3

      = 8 + 27

      = 35
