In an AP with 18 terms the common difference is $-3$−3 . If the nth term is $-5$−5, what is its first term?

46

Step-by-step explanation:

The n th term of an AP  is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here d = - 3 and = - 5 , thus

a₁ + (17 × - 3) = - 5

a₁ - 51 = - 5 ( add 51 to both sides )

a₁ = 46
