Question

11, 8, 5, 2,.....In this A.P. which term is number -46? ​

Answer 1

11 , 8 , 5 , 2 .....is an a.o

here ,

term 1 = t1 = 11

term 2 = t2 = 8

term 3 = t3 = 5

term 4 = t4 = 2

first term = a = 11

common difference = d = t2- t1 = 8 - 11 = -3

Let - 46 be the n th term of this a.p

formula for n th term

t n = a + ( n - 1 ) d

- 46 = 11 + ( n - 1 ) -3

- 46 - 11 = -3n + 3

- 60 = -3n

therefore , n = 20

therefore , - 46 is 20th term of this a.o

hope it helps
