They are: 2+3+5+7 = 17
The sum of the first four prime numbers is 17.
The sum of the first four prime numbers is 17.

Suppose the first term is a, the second is a+r and the nth is a+(n-1)r. Then the sum of the first five = 5a + 10r = 85 and the sum of the first six = 6a + 15r = 123 Solving these simultaneous equations, a = 3 and r = 7 So the first four terms are: 3, 10, 17 and 24
1+3+6+10 =20
It is: 8+16+24+32 = 80
The product of four and four is 16, and the sum of four and four is 8. Dividing the product by the sum, we have 16 divided by 8, which equals 2. Therefore, the quotient is 2.
The sum of four and negative eight is negative four.
To express the sum of four times the opposite of a number and -5, first define the number as ( x ). The opposite of ( x ) is ( -x ). Therefore, four times the opposite of ( x ) is ( 4(-x) ), which simplifies to ( -4x ). The sum of this and -5 can be written as ( -4x - 5 ).
