Question

write the first three terms of the AP where a=2 and d=-5​

Answer 1

Given :

• In an AP, first term, a = 2
• common difference, d = -5

To Find :

• First three terms of AP

Solution :

In an AP,

n$^{th}$ term, a$_n$ = a + (n - 1)d

→ First term, a = 2

→ Second term,

a$_2$ = a + (n - 1)d

a$_2$ = 2 + (2 - 1)-5

a$_2$ = 2 - 5

a$_2$ = -3

→ Third term,

a$_3$ = a + (n - 1)d

a$_3$ = 2 + (3 - 1)-5

a$_3$ = -8

Therefore,

$\boxed{AP = 2, -3, -8}$
