The sum of five different positive integers is 320. The sum of the greatest three integers in this set is 283. The sum of the gr
Nina [5.8K]

Answer:

17

Step-by-step explanation:

Let a,b,c,d,x represent the five integers in Ascending order.

Given;

The sum of five different positive integers is 320

a+b+c+d+x = 320 .......1

The sum of the greatest three integers in this set is 283

c+d+x = 283 .....2

The sum of the greatest and least integers is 119

a+x = 119 ......3

For the largest possible value;

From equation 3, if a is as low as 1,

x = 119-1 = 118

x = 118

For the least possible value;

Subtract equation 2 from 1

a+b = 320-283 = 37

We know that a cannot be higher than b, so the highest possible value of a is;

a = 37-b

a = 37- 19 = 37-19

a = 18

Substituting into equation 3

x = 119-18 = 101

Difference;

∆x = 118-101 = 17

Find the 30th term of an arithmetic progression 5,1015,20​
Ne4ueva [31]

Answer:

150

Step-by-step explanation:

The n th term of an arithmetic progression is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here d = 10 - 5 = 5 and a₁ = 5, hence

a_{30} = 5 + (29 × 5) = 5 + 145 = 150
