Answer:
First no. = 27
Second no. = 29
Third no. = 31
Step-by-step explanation:
First no. = a (smallest no.)
Second no. = a + 2
Third no. = a + 4 ( largest no.)
Given,
3a - 3 + 2(a + 4) = 140
3a - 3 + 2a + 8 = 140
(3a + 2a) + (-3 + 8) = 140
5a + 5 = 140
5a = 140 - 5
5a = 135
a = 135/5
a = 27
First no. = a = 27
Second no. = a + 2 = 29
Third no. = a + 4 = 31
