4, 10, 16, 22,... are the A.P obtained from the 1st differences of a Quadratic Sequence
with a 1st term of 3. Determine the formula for
the sequence & hence its 25th term
plz show step

What is the difference between the numbers in that sequence?
clearly
a = 4, d = 6
term(n) = a + (n-1)d
= 4 + 6(n-1)
= 4 + 6n - 6
= 6n - 2
term(25) = .....
a = 4, d = 6
term(n) = a + (n-1)d
= 4 + 6(n-1)
= 4 + 6n - 6
= 6n - 2
term(25) = .....
