8. Find the sum of first 51 terms of an AP whose second and third terms are 14 and 18respectively.9. If the sum of first 7 terms of an AP is 49 and that of 17 terms is 289, find the sum offirst n terms.251 |
|
Answer» 8. Given, N= 51 a2= 14 A3= 18 To find- S51 Solution- We know that, a2= a+d a3= a+2d So, a+d= 14 - equation 1 a+2d=18 - equation 2 - - - -d= -4 d=4. Substituting value of d in equation 1, we’ll get, a+4=14 a= 14-4 a= 10. Now, Sn=n/2 [2a+ (n-1) d] So, S51= 51/2 [2(10) + (51-1) 4] = 51/2 [20+ (50)(4)] = 51/2[ 20+ 200] = 51/2 [220] = 51 * 110 Answer= 5,610. |

(ii) We have y^2 + √2 = y^2 + √2y^0 It is a polynomial in one variable i.e., y because each exponent of y is a whole number. (iii) We have 3 √t + t√2 = 3 √t^1/2 + √2.t It is not a polynomial, because one of the EXPONENTS of t is 1/2, which is not a whole number. (iv) We have y + y+2/y = y + 2.y^-1 It is not a polynomial, because one of the exponents of y is -1, which is not a whole number. (v) We have x^10+ y^3 + t^50 Here, exponent of every variable is a whole number, but x^10 + y^3 + t^50 is a polynomial in x, y and t, i.e., in three variables.
