Answer 2

Greetings of day !!

Let's find the answer in a step-by-step manner which'll help you understand :)

SOLUTION :

Given,

first term a = 2

second term a2 = 5

∴ common difference d = a2 - a = 5 - 2 = 3

∴ 50th term of A.P.  = a + (n-1)d

                                 = 2 + (50-1)3

                                 = 2 + (49×3)

                                 = 2 + 147

                                 = 149

ANSWER : Hence, 50th term is 149.
