What is the formula to find sum of first n prime numbers?
there isn't a formula for it.you need to calculate it by your own.
What is the sum of the fist 40 even numbers?
You can use the formula for the sum of an arithmetic series to calculate that quickly. (Of course, you can also type the numbers into Excel, and get the sum - but that doesn't scale well - e.g., it won't work well if you are then asked, for instance, to get the sum of the first million even numbers.)

Find 3 consecutive even numbers whose sum is 57?
The sum of two evens is even so the sum of any number of evens is even. It is, therefore, impossible for the sum of three even numbers, whether or not consecutive, to be 57, which is an odd number.
Find the sum of the first 50 even numbers what is the sum?
of all the things i got is 2550
What is the formula to find sum of n even numbers?
Sum = n/2[2Xa1+(n-1)d] where n is last number, a1 is the first number & d is the common difference between the numbers, here d=2 for the even /odd numbers. Sum = n/2 [2Xa1+(n-1)2]
Find three consecutive even numbers that have a sum of 102?
The numbers are 32, 34, and 36.
