answer me fast .... it's urgent ​

Answer 1

Answer:

151 IS THE LAST ONE IN THE GIVEN SEQUENCE

SO WE HAVE TO FIND WHICH TERM IS 151

A=7 A2=10

D=10-7=3

AN=A+(N-1) D

151=7+(N-1) 3

151=7+(3N-3)

151=7+3N-3

151=4+3N

151-4=3N

147=3N

N=147/3

N=49

THEREFORE THEY ARE 49 TERMS IN GIVEN AP

Answer 2

Hey mate !!

The given Ap are 7,10,13.......151

here, a= 7 and a2 =10

so, d = a2 - a1

=> d = 10 - 7

=>d = 3

now, An = a+(n-1)d

=>151=7+(n-1)3

=>(n-1)3=151-7

=>n-1 = 144 /3

=> n= 48+1

=>n= 49

There are mainly 49 terms in the given Ap

:• nth term is 49
