Question

Two A.P’s have same common difference, the first term of the first A.P is 6 and the first term of second A.P is 10 , then the difference of 5th term of two A.P’s i​

Answer 1

Answer:

minus 4 or 4

Step-by-step explanation:

common difference is same

first term of first AP 6

first term of the second ap is 10

A5 is equal to a plus 4 d and a dash 5 is equal to 8 x + 4 da5 - 8-5 That is equal to a + 40 - 8 - 4 d a minus a dash and -4 that is equal to minus 4

Answer 2

Step-by-step explanation:

S1

n=( 2n )(2n+(n−1)d)

S1 30=( 230 )(2×3+(30−1)d)

S1 30 =15(6+29d)

S1 130 =90+435d

For second AP

SS2=( 2n )(2n+(n−1)d)

S2 30 =(230)(2×8+(30−1)d)

S2 30 =15(16+29d)

S2 30 =240+435d

Difference between S1 30−S2 30

=(90+435d)−(240+435d)=150
