Two APs have the same common difference. The difference between their 100th terms is 100, what is the difference between their 1000th terms?

Kepler Telescope.

(ii) 2 , 5/2 , 3 , 7/2 d = 5/2 - 2= 1/2 (iii) -1.2, -3.2 , -5.2 d = -3.2 + 1.2 = -2 (iv) -10 , -6 , -2 , 2 d...

(a) Lithium (Li), sodium (Na), and potassium (K) have a single electron in their outermost shells. (b) Magnesium (Mg) and calcium (Ca) have two electrons in their outermost shells. (c) Neon (Ne),...

(a) In evolutionary terms, we have more in common with a Chinese school boy.

Solution: Here, a=-37, d=4 and n=12 S=12/2(2x-37+4 x11)=6x-30=-180

Solution: here a = a = 0.6, d=1.1 and n= 100 s=100/2(0.6+1.1 x99) = 50 x109.5=5475

Given that the nth term of the A.P. is 7n -5 So 100th term will be 7 ( 100 ) - 5 = 695

Solution: In the first AP a = 63 and d = 2 In the second AP a = 3 and d = 7 As per question, 63+2(n-1) = 2+ 7(n-1) Or, 61 = 5...
