Show that any positive odd integer is of the form 6q+1,or 6q+3,or 6q+5, where q is some integer |
| Answer» Let a be any positive integer and b = 6∴ by Euclid’s division lemmaa = bq + r, 0≤ r and q be any integer q ≥ 0∴ a = 6q + r,where, r = 0, 1, 2, 3, 4, 5If a is even then then remainder by division of 6 is 0,2 or 4Hence r=0,2,or 4or A is of form 6q,6q+2,6q+4As, a = 6q = 2(3q), ora = 6q + 2 = 2(3q + 1), ora = 6q + 4 = 2(3q + 2).If these 3 cases a is an even integer.but if the remainder is 1,3 or 5 then r=1,3 or 5or A is of form 6q+1,,6q+3 or,6q+5Case 1:a = 6q + 1 = 2(3q) + 1 = 2n + 1,\xa0Case 2: a = 6q + 3 = 6q + 2 + 1,= 2(3q + 1) + 1 = 2n + 1,\xa0Case 3: a = 6q + 5 = 6q + 4 + 1= 2(3q + 2) + 1 = 2n + 1This shows that odd integer is of the form 6q + 1, or 6q + 3, or 6q + 5, where q is some integer. | |

If the 2nd term of an A.P is 8 and the 5th term is 17 find its 19th term? |
|
Answer» 59. If 2nd term is 8 So..a,a+d,a+2d....a+d=8................ Equation no.1Then...The 5th term is 17...Again same ...But now it\'s 5th term so ....a+4d=a5 I.e. a+4d=17................... Equation no.2Therefore....From 1 and 2a+d=8a+4d=17Now by elimination method....And subtracting Equation.no.1 from 2 ....We get ......Now a will be cancelled out ....So ...Remaining is...-3d=-9Therefore... d=3....... Equation.no.3.Now putting the value of d in 1 equation ...We get...a+d=8,a+3=8a=8-3Therefore...a=5...Now at the last ....U got a and d so form the AP and get the answer....No no don\'t form AP ...Then we will ...Put all the values in the formula An=a+(n-1)dA19=5+(19-1)×3A19=5+18×3A19=5+54A19=59Therefore....19th term of an AP is 59..., 59 Sorry 59 is correct. Its 59 54. |
