1.	For what value of n the nth term of the AP: 74, 77, 80, and 14, 20, 26,... areequal.
Answer» ong>Answer: 21 st Step-by-step explanation: GIVEN, AP1 : 74,77,80.... and AP2 : 14,20,26.... a=74 a'=14 d=77-74=3 d'=20-14=6 ATQ: $a_{n}$ = $a_{n}$ ' a + (n-1)d=a' + (n-1)d' 74 + (n-1)3 =14 + (n-1)6 60 + 3n-3 -6N +6=0 63=3n n=21 thus for the 21 st term the nth term of the APs will be equal. hope this HELPS:)

ong>Answer:

21 st

Step-by-step explanation:

GIVEN,

AP1 : 74,77,80.... and AP2 : 14,20,26....

a=74 a'=14

d=77-74=3 d'=20-14=6

ATQ:

$a_{n}$ = $a_{n}$ '

a + (n-1)d=a' + (n-1)d'

74 + (n-1)3 =14 + (n-1)6

60 + 3n-3 -6N +6=0

63=3n

n=21

thus for the 21 st term the nth term of the APs will be equal.

hope this HELPS:)
