IF U KNOW THE ARTHEMATIC PROGREESION IT WILL COME EASIER.....
Step-by-step explanation:
Sn=437
a=-4
and d=-1-(-4)=3 BECAZ D=2ND TERM MINUS FIRST TERM
Sn=n/2(2a+(n-1)d) ITS FORMULA
437=n/2(2(-4)+(n-1)3
437=n/2(-8+3n-3)
437=n/2(-11+3n)
874=n(-11+3n)
874=-11n+3n^2
3n^2-11n-874=0
THERE FORE N= -B±√B^2-4AC/2A
IF WE DO THIS N WILL COME THE N IS YOU'RE ANSWER
THANK YOU
PLEASE MARK ME AS BRAINLIEST
