Find the 4th and 7th term of the sequence whose nth term is n(n−1)

Step 1: Write down the given formula for the nth term. The nth term of the sequence is given by: aₙ = n(n−1); Step 2: Calculate the 4th term by substituting n = 4 into the formula. a₄ = 4(4-1); a₄ = 4(3); a₄ = 12; Step 3: Calculate the 7th term by substituting n = 7 into the formula. a₇ = 7(7-1); a₇ = 7(6); a₇ = 42 The 4th term is 12 and the 7th term is 42.

Solved: Find the 4th and 7th term of the sequence whose nth…

Write down the given formula for the nth term.
The nth term of the sequence is given by:
aₙ = n(n-1)
Calculate the 4th term by substituting n = 4 into the formula.
a₄ = 4(4-1)
a₄ = 4(3)
a₄ = 12
Calculate the 7th term by substituting n = 7 into the formula.
a₇ = 7(7-1)
a₇ = 7(6)
a₇ = 42
