Question

Find the no of mulitplies of 3between 100and 200

Answer 1

They are 102, 105, 108, 111, 114, 117, 120, 123, 126, 129, 132, 135, 138, 141, 144, 147, 150, 153, 156, 159, 162, 165, 168, 171, 174, 177, 180, 183, 186, 189, 192, 195 & 198. Divide 100 and 200 by 3. You get 33 and a bit and 66 and a bit.

Answer 2

Answer:

33.

Step-by-step explanation:

The total numbers b/w 100 and 200 = 100

the first multiple of 3 in that = 102

so if an AP is formed, then a= 102

d = 3

the last term in this AP is 198

a n = 198 = a + [n-1] d

102+ [ n-1] 3= 198

198 - 102 = 3n- 3

96 + 3 = 3n

n = 99/3 = 33

there are 33 multiples of 3 b/w 100 and 200.

Hope this answer can help you dear.
