Question

for an A.P 1st term is -10 and common difference is -3 find 2nd and 3rd term​

Answer 1

Answer:

a = -10

d = -3

a2 = a+d = -10 -3 = -13

a3 = a + 2d = -10 +2(-3) = -10 - 6 = -16

Answer 2

Solution

Given :-

• a = -10 ,
• d = -3

Find :-

• 2nd & 3rd terms of A.P.

Explanation

Using Formula

★nth terms = a + (n - 1)d

For 2nd terms

==> 2nd terms = -10 + (2 - 1)×(-3)

==> 2nd terms = -10 - 3

==> 2nd terms = -13

Now, For 3rd terms

==> 3rd terms = -10 + ( 3 - 1)×(-3)

==> 3rd terms = -10 + 2 × -3

==> 3rd terms = -10 - 6

==> 3rd terms = -16

Hence

• 2nd terms will be = -13
• 3rd terms will be = -16
