Question

23,46,69,..….. , 230. find common difference.

Answer 1

Hii ☺ !!



AP = 23 , 46 , 69 , ... , 230




Here,

First term ( T1) = 23


Second term ( T2) = 46

And,

Third term ( T3 ) = 69


Therefore,


Common difference ( d ) = T2 - T1 = 46-23 = 23.

Answer 2

according to questions.

here

we calculate common difference (d)

using formula .

a2 - a1 = d

a3 - a2 = d

in other words here list of numbers a1 , a2 , a3 ..... an

a2 = a1 + d

a3 = a2 + d

but here find d then using formula

a2 - a1 = d

a3 - a2 = d

here

a1 = 23

a2 = 46

a3 = 69

last term n = 230

find common difference (d)

d = a2 - a1

46 - 23 = 23

next

d = a3 - a2

69 - 43 = 26

d = 23 , 26

here difference of any two consecutive terms is same as the given sequence in AP term.
