Question

Q.5. Write first two terms of the A.P. when a = 10 and d=10​

Answer 1

Solution

Given :-

• a = 10, d = 10

Find :-

• first & second terms of A.P.

Explanation

Using Formula

★ an = a + (n-1)d

Calculate second terms

➡a2 = 10 + (2-1)×10

➡a2 = 10 + 10

➡a2 = 20

Now, Calculate third terms

➡ a3 = 10 + (3-1)×10

➡a3 = 10 + 2 × 10

➡a3 = 10 + 20

➡a3 = 30

Hence

• First terms of A.P. = 10
• Second terms of A.P.= 20
• Third terms of A.P. = 30

Answer 2

given : a=10

d=10

the terms of an a.p by the method

a,a+d,a+2d,a+3d

so, 10,20

are the fist two terms of the ap..........
