Answer 2

Answer:

three digits numbers from 150 to 200 are ,. 150,151,152............200.

here ,a= t1 =150.

t2=152,t3=152,

and tn=200

tn= a+ (n-1)d.........(formula)

200=150+(n-1)1

200-150=n-1

50=n-1

50+1=n

51=n

n=1

there are 51 numbers from 150 to 200.

sn=n/2[2a+(n-1)d]

s51=51/2[2*150+(51-1)1]

=25.5[300+50]

=25.5*350

=8925

for the sum of all 3 digit numbers from 150 to 200 is 8925.
