Question

if a=11, d=2 in an A.P, then t2 and t3 is ​

Answer 1

Given : a = 11 , d = 2 in AP

To Find : t₂ and t₃

Solution:

in an AP

tₙ = a + (n - 1) d

a = 11

d = 2

t₂  = 11 + (2 - 1) (2)

=>  t₂  = 11 + (1) (2)

=>  t₂  = 11 +  (2)

=>  t₂  = 13

t₃ = 11 + (3 - 1) (2)

=>  t₃ = 11 + (2) (2)

=>  t₃  = 11 + 4

=>  t₃  = 15

t₂ = 13  and t₃ = 15
