Answer 1

Answer: 126,133,140

You can try this for small series but if anyone ask for no. of multiples in a big series than try A.P

As from:99-999

no. which are divisible by 7 to do it find first&last

they  are:105&994

first find the place of last digit:a+(n-1)d=994

a=1st term

n= no. of term

d= common difference

105(n-1)7=994

from here n will be no of terms
