can any one tell me the answer for this?
1) 1, 2, 3, 5, 7, 11, __?
2) ___, ayw, gec, mki, sqo
Read Solution (Total 8)
-
- 1) 1, 2, 3, 5, 7, 11, x
Divide it into 2 groups...
(1, 3, 7, x) (2, 5, 11)
2nd group
2 + (3) = 5
5 + (3*2) = 11
1st group
1 + (2) = 3
3 + (2*2) = 7
7 + (4*2) = 15
Ans : 15
(2) ___, ayw, gec, mki, sqo
1st letter of each word differ by 6...
a+6=g, g+6=m, m+6=s
So 1st letter of 1st word ll be a-6=u
2nd nd 3rd letters differ by 2...
ayw => a-2=y, y-2=w
Similarly u-2=s, s-2=q
Ans : usq - 10 years agoHelpfull: Yes(15) No(0)
- "1" is not a prime no.
An integer >1 is called a prime number if its only positive divisors are one and itself. - 10 years agoHelpfull: Yes(2) No(0)
- 1) 1, 2, 3, 5, 7, 11 all prime numbers.
so next is 13(Ans.).
2) ___, ayw, gec, mki, sqo
1st letter of each word differ by 6.
a+6=g, g+6=m, m+6=s
So 1st letter of 1st word ll be a-6=u
2nd and 3rd letters differ by 2.
ayw => a-2=y, y-2=w
Similarly u-2=s, s-2=q
Ans : usq
- 10 years agoHelpfull: Yes(1) No(1)
- 1) 1, 2, 3, 5, 7, 11 all prime numbers.
so next is 13(Ans.).
2) ___, ayw, gec, mki, sqo
1st letter of each word differ by 6.
a+6=g, g+6=m, m+6=s
So 1st letter of 1st word ll be a-6=u
2nd and 3rd letters differ by 2.
ayw => a-2=y, y-2=w
Similarly u-2=s, s-2=q
Ans : usq - 10 years agoHelpfull: Yes(1) No(1)
- answer: 15

2nd group
2 + (3) = 5
5 + (3*2) = 11
1st group
1 + (2) = 3

(2) ___, ayw, gec, mki, sqo
1st letter of each word differ by 6...
a+6=g, g+6=m, m+6=s
So 1st letter of 1st word ll be a-6=u
2nd nd 3rd letters differ by 2...
ayw => a-2=y, y-2=w
Similarly u-2=s, s-2=q
Ans : usq - 10 years agoHelpfull: Yes(1) No(0)
- 1)13 order of odd numbers
2)usq - 10 years agoHelpfull: Yes(0) No(1)
- 1)13 why bcoz all cosetutive prime nos
2)usq
by substracting 2 we get last digit nd by adding 2 we get the first no.
by adding 6 to middle no we gwt nwxt middle no.
so the middle no is "s".
- 10 years agoHelpfull: Yes(0) No(1)
- 15(1 is neither prime nor composite)
usq - 10 years agoHelpfull: Yes(0) No(0)
