Question

Is 100 is a term of Arithmetic sequance 21,32,43.....
what about 10,000​

Answer 1

Answer:

given a = 21, d = 11

to find if 100 is a term in this A.P.

let 100 be a term

aₙ = 100

therefore 100 = [21 + (n - 1) 11]

100 = 21 + 11n - 11

100 = 10 + 11n

11n = 100 - 10

11 n = 90

n = 90/11

n = 8 ¹´₁₁

as n is not a whole number, 100 is not a term in the given A.P.

Answer 2

Answer:

100 is not a term of given ap

Step-by-step explanation:

because the value of n is not coming as an integer

here the first term is 21 and the common difference is 11

thus we can see that 100 is not the part of the series
