Question

Find the 23rd term of 2,4,6,8,...

Answer 1

Hii ☺!!



AP = 2 , 4 , 6 , 8 .....


Here,

First term ( a ) = 2

Common difference ( d ) = 4 - 2 = 2








Therefore,


23rd term of the given AP = a + 22d = 2 + 22 × 2 = 2 + 44 = 46 .

Answer 2

a = 2
d = 2
Tn = a + (n-1)d
T23 = 2 + (23 - 1)2
T23 = 2 + (22)2
T23 = 2 + 44
= 46
23 rd Term is 46
