Answer 1

Answer:

there are 88 terms that are divisible by 2&5 between 112&998

Step-by-step explanation:

Between 112&998, 1st term which is divided by 2&5(2×5) is 120 and the last term is 990

A.P=120,130,140-------‐---990

a=120

d=130-120=10

d=10

an=990

n=?

an=a+(n-1)×d

990=120+(n-1)×10

990-120=(n-1)×10

870÷10=n-1

n-1=87

n=87+1

n=88

Hence there are 88 terms that are divisible by 2&5 between 112&998
