Which of these are pairs co primes from 1to100 |
|
Answer» Answer: The “perfect” co-primes are: 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97. Quora Step-by-step EXPLANATION: In number theory, two integers a and B are said to be relatively PRIME, mutually prime, or COPRIME if the only positive integer that divides both of them is 1. Consequently, any prime number that divides one does not divide the other. This is equivalent to their greatest COMMON divisor being 1. Wikipedia |

5th term of an AP is 5 times the first term and the 12th term exceeds the 7th term by 15, find the AP. |
|
Answer» Answer: 3,6,9,12,....... Step-by-step explanation: given: 5th term of an AP is 5 times the FIRST term 12th term exceeds the 7th term by 15 to find: find the AP assumptions: let a be the first term , and d be the COMMON difference solution: series is a,a+d,a+2d,a+3d,............... clearly if you see second term you can tell that it is of the form a+(n-1)d where n tells which term it is (EITHER 1st or 2nd ..) so 5th term is a+(5-1)d = a+4d given 5th term of an AP is 5 times the first term so a+4d = 5*a ==>4d = 4A ==> d = a 12th term is a+ (12-1)d = a+11d 7th term is a+(7-1)d = a+6d given 12th term exceeds the 7th term by 15 therefore a+11d = (a+6d) + 15 ===> 5d =15 ==> d= 3 form both the UNDERLINED we can get a =d = 3 so series is 3,6,9,12,....... |

How many numbers betwewn 2222 to 3333 are divisible by 7 |
|
Answer» Answer: 159 numbers betwewn 2222 to 3333 are divisible by 7 Step-by-step explanation: First no divisible by 7 between 2222 to 3333 is 2226 So the no will be 2226,2233,..... when we divide by 7 the remainder=1 so the last no=3333-1=3332 Hence an Ap is FORMED where a=2226,d=7,an=3332, N=? we KNOW that an=a+(n-1)7 3332=2226+(n-1)7 7(n-1)=3332-2226 =1106 n-1=1106/7=158 n=158+1 =159 |
