Question

the 6th term of an arithmetic sequence is 24. what is the sum of the 5th and 7th terms

Answer 1

no way to determine without knowing the value of another term

Answer 2

its 48

Answer 3

24 = a1 + d(23)

we have one equation in 2 unknowns

Answer 4

let first term be a.
let difference be d
so for sixth term we have
a+5d=24

so 5th term= a+4d
7th term= a+6d

so 5th term +7th term = a+4d+a+6d =2a+10d =2(a+5d)=2*24 =48

Answer 5

thx

Answer 6

hmm, 48 does make sense ....

Answer 7

in ap difference is same between consecutive nos so,
T6-T5=T7-T6
2T6=T5+T7
2*24=48
48 IS ANSWER

Answer 8

24+n + 24 - n = 48 regardless of n ... good job
