Question

50,100,150,200,...,Find the nth term of the given AP.

Answer 1

a = 50

d = 100 - 50 = 50

Tn = a +(n-1) d

= 50 + (n-1) 50

= 50 + 50n - 50

= 50n

Answer 2

Hi,

Here is your answer,

a(First term) = 50

d(Common difference) 2nd Term - 1st Term = 100 - 50 = 50

Tn = a+(n-1)×d ( Using nth term of an A.P Formula)

→ 50+(n-1) 50

→ 50+50n-50

→ 50 n

Hope it helps you !
