Answer 2

How to find D ?

To find the "nth" term of an arithmetic sequence, start with the first term, a(1). Add to that the product of "n-1" and "d" (the difference between any two consecutive terms). For example, take the arithmetic sequence 3, 9, 15, 21, 27.... a(1) = 3. d = 6 (because the difference between consecutive terms is always 6.

d is the difference.

How to find A ?

A is the first term .

Question:-

The sequence-10-13.-16..19........... is an A.P. find a & d.

Required Answer:-

D = a2 - a1

= 13 - 10

= 3

Therefore , D= 3

A= 10

( as it is given in the question)

Formulas:-

a2 = a + d

a3 = a + 2d

a4 = a + 3D

....

An = a1 + (n-1) d

an = the nᵗʰ term in the sequence

a1 = the first term in the sequence

d = the common difference between terms
