Question

which term of the AP 23,46,69...is 437​

Answer 1

Answer is 19th term

Step-by-step explanation:

In the given AP, we have

first term =23 and common difference = (46-23)=23.

a=23 and d = 23. Then,

Tn = 437 => a+(n-1)d =437

=>23+(n-1)*23= 23+23n-23= 437

=> 23n =437

=> n=437/23=19

=>n=19

Hence, the 19th term of the given AP is 437.

Which term of The AP 23 , 46 , 69 , .... is 437

${\mathtt{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

$\large\underline\blue{\sf Given , \: 23 \: 46 \: 69 \: . \: . \: . \: 437 :-}$

A1 = 23

D = A1 -A2

d = 46 - 23

An = 437

Using Formula of AP -:

An = A1 + (n-1)d

437 = 23 +( n - 1) 23

437 -23 = (n - 1) 23

414 = (n-1)23

414/23 =n-1

18 = n-1

n = 18+1

n = 19

Hence 19th term of An given AP is 437 .
