I think of a prime number, and add it to the next larger prime number.
I continue with this twice more. I have now worked out the sum of four consecutive primes. This total comes to 202.
Solving this will involve some trial and error or guesswork. There could be less hard work if you think about it first of all.
It should take a lot less than five minutes to find the answer ~ you will know yourself whether it is right or wrong.
If some of the words are new or strange ~ here is some help ~
Prime Numbers ~ are numbers which do not appear as answers in your multiplication tables ~ the times tables. You have to do a fair bit of trial and error to work out prime numbers. Is 17 a prime number? Try 2x8=16, 2x9=18...it is not divisible by 2. Next try ~ 3x5=15 ~ 3x6=18 ~ nor 3. Next try 5x3=15 ~ 5x4=20. ~ Next try 7x2=14 ~ 7x3=21. Next is 11...and that does not work either.So 17 is a prime number. All this is much easier if you know your times-tables well
Sum ~ This word is often used when talking about questions ~ problems ~ tasks ~ as in 'I am doing some sums'. Mathematicians use the word to mean specifically to mean adding-up tasks. The sum of the digits two, three, four is 2+3+4 and the sum ~ summation ~ is nine.
Consecutive means 'following on in sequence'. You might ask 'What sequence?' Well~ that has to be made clear at the same time as using the word consecutive. 13~17~19care consecutive prime numbers ~ starting with thirteen. 12~14~16~18 are consecutive even numbers, starting a 12.
Solve ~ means 'find the solution' to the task ~ puzzle ~ question ~ problem
Trial and error ~ guesswork. One way to tackle this problem would be to think of any prime ~ say 13 ~ then move on to 17 ~ add them up ~ and so on. That would be your first guess or try or trial. It will ~ sadly ~ be in error for the question as set. Some people are able to work out the smaller prime numbers very quickly ~ they have maybe even learnt them. Larger primes take more thought ~ or trials and successes perhaps!
